With podman play kube, podman would always attempt to
pull if the image has the :latest tag. But this would
fail if the image was built locally and given latest
as the tag. Images build with podman and buildah have
localhost as the domain, so check if the domain is localhost.
If that is the case, then don't attempt a pull.

This adds a new command, 'podman network reload', to reload the
networks of existing containers, forcing recreation of firewall
rules after e.g. `firewall-cmd --reload` wipes them out.
Under the hood, this works by calling CNI to tear down the
existing network, then recreate it using identical settings. We
request that CNI preserve the old IP and MAC address in most
cases (where the container only had 1 IP/MAC), but there will be
some downtime inherent to the teardown/bring-up approach. The
architecture of CNI doesn't really make doing this without
downtime easy (or maybe even possible...).
At present, this only works for root Podman, and only locally.
I don't think there is much of a point to adding remote support
(this is very much a local debugging command), but I think adding
rootless support (to kill/recreate slirp4netns) could be
valuable.

* Update docs and an several new tests.
* Includes many fixes, most notably, the look-up of volumes and mounts.
Breaking changes:
* Podman is now expecting that container-destination paths exist.
Before, Podman created the paths if needed. Docker does not do
that and I believe Podman should not either as it's a recipe for
masking errors. These errors may be user induced (e.g., a path
typo), or internal typos (e.g., when the destination may be a
mistakenly unmounted volume). Let's keep the magic low for such
a security sensitive feature.

The network ID is not stored. It is just the sha256 hash from
the network name. There is a risk of a potential hash collision.
However it's very unlikely and even if we hit this it will
complain that more than network with this ID exists.
The main benefit is that the compat api can have proper
network ID support. Also this adds the support for
`podman network ls --format "{{.ID}}"` and `--filter id=<ID>`.
It also ensures that we can do network rm <ID> and network
inspect <ID>.
Since we use a hash this commit is backwards compatible even for
already existing networks.

This should replace the handwritten completion scripts

less likley that completions and code are out of sync.
We can now create the scripts with
- podman completion bash
- podman completion zsh
- podman completion fish
To test the completion run:
source <(podman completion bash)
The same works for podman-remote and podman --remote and
it will complete your remote containers/images with
the correct endpoints values from --url/--connection.
The completion logic is written in go and provided by the
cobra library. The completion functions lives in
`cmd/podman/completion/completion.go`.
The unit test at cmd/podman/shell_completion_test.go checks
if each command and flag has an autocompletion function set.
This prevents that commands and flags have no shell completion set.
This commit does not replace the current autocompletion scripts.

This is a continuation of #8189 and #8085.
When doing a `docker build` command, if the `--pull` command is not specified
or set to `false` the pullOption used is `PullifMissing`. This causes the
build to pull the image only if it is not present in local storage. It also will
raise an error if the image is not found in the registry (or the registry is down),
even if the image is present in local storage.
If the `--pull` command IS specified or specified with an argument of `true`, the
build will always pull the image from the registries. This uses the pullOption
`PullAlways`. It also will raise an error if the image is not found in the registry,
even if the image is present in local storage.
These changes now brings the pull functionality for `podman build` into line
with `docker build`.
However, I consider this to be a breaking change. Previously if you did
`podman build --pull`, `podman build` or `podman build --pull = true`, then
the image would be pulled from the registry if there was not an image in
local storage or if the image in the registry was newer than the one in
local storage. An error would *NOT* be raised if there was not an image in
the registry or the registry was down as long as there was a copy in the local
storage. An error would be raised if the image could not be retrieved from
both the registry and local storage. This is the PullOption `PullIfNewer`.
I believe this also differs from what Buildah does at this time but I'm too
beat to chase that down at the moment.
Personally I'd like to use the `PullIfNewer` for at least `--pull` and
`--pull=true` so that you don't get an error if the registry has a network
hiccup and the image is already stored locally. But this differs from Docker.
I'd like to post scrum about this at our next stand up to make sure we're
all on the same page about the ramifications of this change.

Docker and CNI have very different ideas of what 0.0.0.0 means.
Docker takes it to be 0.0.0.0/0 - that is, bind to every IPv4
address on the host. CNI (and, thus, root Podman) take it to mean
the literal IP 0.0.0.0. Instead, CNI interprets the empty string
("") as "bind to all IPs".
We could ask CNI to change, but given this is established
behavior, that's unlikely. Instead, let's just catch 0.0.0.0 and
turn it into "" when we parse ports.

There are many use cases where you want to just mount an image
without creating a container on it. For example you might want
to just examine the content in an image after you pull it for
security analysys. Or you might want to just use the executables
on the image without running it in a container.
The image is mounted readonly since we do not want people changing
images.

Podman is committed to inclusivity, a core value of open source. Historically, there have been technology terms that are problematic and divisive, and should be changed. We are currently taking time to audit our repository in order to eliminate such terminology, and replace it with more inclusive terms. We are starting where we can, with our own code, comments, and documentation. However, such terms may be used in dependencies, and must be used in our repositories at the current moment for compatibility. Podman will change these terms in our repo as soon as new and better terminology is available to us via our dependencies.

--sdnotify container|conmon|ignore
With "conmon", we send the MAINPID, and clear the NOTIFY_SOCKET so the OCI
runtime doesn't pass it into the container. We also advertise "ready" when the
OCI runtime finishes to advertise the service as ready.
With "container", we send the MAINPID, and leave the NOTIFY_SOCKET so the OCI
runtime passes it into the container for initialization, and let the container advertise further metadata.
This is the default, which is closest to the behavior podman has done in the past.
The "ignore" option removes NOTIFY_SOCKET from the environment, so neither podman nor
any child processes will talk to systemd.
This removes the need for hardcoded CID and PID files in the command line, and
the PIDFile directive, as the pid is advertised directly through sd-notify.

podman inspect is problematic because there can be naming clashes. Also,

I didn't believe that this was actually legal, but it looks like
it is. And, unlike our previous understanding (host port being
empty means just use container port), empty host port actually
carries the same meaning as `--expose` + `--publish-all` (that
is, assign a random host port to the given container port). This
requires a significant rework of our port handling code to handle
this new case. I don't foresee this being commonly used, so I
optimized having a fixed port number as fast path, which this
random assignment code running after the main port handling code
only if necessary.

When running under systemd there is no need to create yet another
cgroup for the container.
With conmon-delegated the current cgroup will be split in two sub
cgroups:
- supervisor
- container
The supervisor cgroup will hold conmon and the podman process, while
the container cgroup is used by the OCI runtime (using the cgroupfs
backend).

New functionality in hack/man-page-checker: start cross-
referencing the man page 'Synopsis' line against the
output of 'podman foo --help'. This is part 1, flag/option
consistency. Part 2 (arg consistency) is too big and will
have to wait for later.
flag/option consistency means: if 'podman foo --help'
includes the string '[flags]' in the Usage message,
make sure the man page includes '[*options*]' in its
Synopsis line, and vice-versa. This found several
inconsistencies, which I've fixed.
While doing this I realized that Cobra automatically
includes a 'Flags:' subsection in its --help output
for all subcommands that have defined flags. This
is great - it lets us cross-check against the
usage synopsis, and make sure that '[flags]' is
present or absent as needed, without fear of
human screwups. If a flag-less subcommand ever
gets extended with flags, but the developer forgets
to add '[flags]' and remove DisableFlagsInUseLine,
we now have a test that will catch that. (This,
too, caught two instances which I fixed).
I don't actually know if the new man-page-checker
functionality will work in CI: I vaguely recall that
it might run before 'make podman' does; and also
vaguely recall that some steps were taken to remedy
that.

We initially believed that implementing this required support for
restarting containers after reboot, but this is not the case.
The unless-stopped restart policy acts identically to the always
restart policy except in cases related to reboot (which we do not
support yet), but it does not require that support for us to
implement it.
Changes themselves are quite simple, we need a new restart policy
constant, we need to remove existing checks that block creation
of containers when unless-stopped was used, and we need to update
the manpages.

When the container uses journald logging, we don't want to
automatically use the same driver for its exec sessions. If we do
we will pollute the journal (particularly in the case of
healthchecks) with large amounts of undesired logs. Instead,
force exec sessions logs to file for now; we can add a log-driver
flag later (we'll probably want to add a `podman logs` command
that reads exec session logs at the same time).
As part of this, add support for the new 'none' logs driver in
Conmon. It will be the default log driver for exec sessions, and
can be optionally selected for containers.
Great thanks to Joe Gooch (mrwizard@dok.org) for adding support
to Conmon for a null log driver, and wiring it in here.

Add a `--replace` flag to the `pod create` command. If another pod with
the same name already exists, it will be replaced and removed.
Adding this flag is motivated by #5485 to make running Podman in systemd
units (or any other scripts/automation) more robust. In case of a
crash, a pod may not be removed by a sytemd unit anymore. The
`--replace` flag allows for supporting crashes.
Note that the `--replace` flag does not require the `--name` flag to be
set, so it can be set unconditionally in `podman generate systemd`.
