It took a lot to figure out exactly how this should work, but I
think I finally have it. My initial versions of this created the
directory with the same owner as the user the container was run
with, which was rather complicated - but after review against
Docker, I have determined that is incorrect, and it's always made
as root:root 0755 (Ubuntu's Docker, which I was using to try and
test, is a snap - and as such it was sandboxed, and not actually
placing directories it made in a place I could find?). This makes
things much easier, since I just need to parse out source
directories for binds and ensure they exist.

Docker has, for unclear reasons, three separate fields in their
Create Container struct in which volumes can be placed. Right now
we support two of those - Binds and Mounts, which (roughly)
correspond to `-v` and `--mount` respectively. Unfortunately, we
did not support the third, `Volumes`, which is used for anonymous
named volumes created by `-v` (e.g. `-v /test`). It seems that
volumes listed here are *not* included in the remaining two from
my investigation, so it should be safe to just append them into
our handling of the `Binds` (`-v`) field.

There exists a unit test to ensure that shell completion functions are
defined. However there was no check about the quality of the provided
shell completions. Lets change that.
The idea is to create a general test that makes sure we are suggesting
containers,pods,images... for the correct commands. This works by
reading the command use line and checking for each arg if we provide
the correct suggestions for this arg.
It includes the following tests:
- flag suggestions if [options] is set
- container, pod, image, network, volume, registry completion
- path completion for the appropriate arg KEYWORDS (`PATH`,`CONTEXT`,etc.)
- no completion if there are no args
- completion for more than one arg if it ends with `...]`
The test does not cover completion values for flags and not every arg KEYWORD
is supported. This is still a huge improvement and covers most use cases.
This test spotted several inconsistencies between the completion and the
command use line. All of them have been adjusted to make the test pass.
The biggest advantage is that the completions always match the latest
command changes. So if someone changes the arguments for a command this
ensures that the completions must be adjusted.

Allow automatic generation for shell completion scripts
with the internal cobra functions (requires v1.0.0+).
This should replace the handwritten completion scripts
and even adds support for fish. With this approach it is
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.

In `podman inspect` output for containers and pods, we include

With remote podman, the generated create commands were incorrect
since we sourced directly from os.Args on the server side, which
was guaranteed to be `podman system service` (or some variant
thereof). The solution is to pass the command along in the
Specgen or PodSpecgen, where we can source it from the client's
os.Args.
This will still be VERY iffy for mixed local/remote use (doing a
`podman --remote run ...` on a remote client then a
`podman generate systemd --new` on the server on the same
container will not work, because the `--remote` flag will slip
in) but at the very least the output of `podman inspect` will be
correct. We can look into properly handling `--remote` (parsing
it out would be a little iffy) in a future PR.

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

These were part of Podman v1.9, but were lost in the transition
to using Specgen to create containers. Most resource limits are
checked via the sysinfo package to ensure they are safe to use
(the cgroup is mounted, kernel support is present, etc) and
removed if not safe. Further, bounds checks are performed to
ensure that values are valid.
Ensure these warnings are printed client-side when they occur.
This part is a little bit gross, as it happens in pkg/infra and
not cmd/podman, which is largely down to how we implemented
`podman run` - all the work is done in pkg/infra and it returns
only once the container has exited, and we need warnings to print
*before* the container runs. The solution here, while inelegant,
avoid the need to extensively refactor our handling of run.
Should fix blkio-limit warnings that were identified by the FCOS
test suite.

This started as a small fix to `podman inspect` where a container
and image, with the same name/tag, were present, and
`podman inspect` was run on that name. `podman inspect` in 1.9
(and `docker inspect`) will give you the container; in v2.0, we
gave the image. This was an easy fix (just reorder how we check
for image/container).
Unfortunately, in the process of testing this fix, I determined
that we regressed in a different area. When you run inspect on
a number of containers, some of which do not exist,
`podman inspect` should return an array of inspect results for
the objects that exist, then print a number of errors, one for
each object that could not be found. We were bailing after the
first error, and not printing output for the containers that
succeeded. (For reference, this applied to images as well). This
required a much more substantial set of changes to properly
handle - signatures for the inspect functions in ContainerEngine
and ImageEngine, plus the implementations of these interfaces,
plus the actual inspect frontend code needed to be adjusted to
use this.

Add a `--replace` flag to the `container {create,run}` commands.
If another container 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 container may not be removed by a sytemd unit anymore. The
`--replace` flag allows for supporting crashes.

Two areas needed tweaking to accomplish this: port parsing and
binding ports on the host.
Parsing is an obvious problem - we have to accomodate an IPv6
address enclosed by [] as well as a normal IPv4 address. It was
slightly complicated by the fact that we previously just counted
the number of colons in the whole port definition (a thousand
curses on whoever in the IPv6 standard body decided to reuse
colons for address separators), but did not end up being that
bad.
Libpod also (optionally) binds ports on the host to prevent their
reuse by host processes. This code was IPv4 only for TCP, and
bound to both for UDP (which I'm fairly certain is not correct,
and has been adjusted). This just needed protocols adjusted to
read "tcp4"/"tcp6" and "udp4"/"udp6" based on what we wanted to
bind to.

Systemd enablement has to happen on the server side, since we need
check if the image is running systemd.
Also need to make sure user setting the StopSignal is not overriden on the
server side. But if not set and using systemd, we set it correctly.

We were picking up defaults from the client's containers.conf,
which broke pod namespaces. The server-side code already checks
containers.conf when not explicitly overridden by the user, or by
the container being part of a pod (the last bit being our bug).
This only manifested on systems with a containers.conf installed,
so RHEL 8 and Fedora 32 (which means our F32 CI VMs likely should
have caught it, but didn't, which is concerning).
This prevents defaults for these flags being shown, but they were
incorrect anyways for `podman-remote`, so I'm not terribly
concerned.

There are three different priorities for applying env variables:

Add the `podman generate kube` and `podman play kube` command. The code
has largely been copied from Podman v1 but restructured to not leak the
K8s core API into the (remote) client.
Both commands are added in the same commit to allow for enabling the
tests at the same time.
Move some exports from `cmd/podman/common` to the appropriate places in
the backend to avoid circular dependencies.
Move definitions of label annotations to `libpod/define` and set the
security-opt labels in the frontend to make kube tests pass.

To try and identify differences between Podman v1.9 and master,
I ran a series of `podman run` commands with various flags
through each, then inspecting the resulting containers and diffed
the inspect JSON between each. This identified a number of issues
which are fixed in this PR.
In order of discovery:
- Podman v2 gave short names for images, where Podman v1 gave the
fully-qualified name. Simple enough fix (get image tags and use
the first one if they're available)
- The --restart flag was not being parsed correctly when a number
of retries was specified. Parsing has been corrected.
- The -m flag was not setting the swap limit (simple fix to set
swap in that case if it's not explicitly set by the user)
- The --cpus flag was completely nonfunctional (wired in its
logic)
Tests have been added for all of these to catch future
regressions.

As part of this, make a major change to the type we use to
represent port mappings in SpecGen (from using existing OCICNI
structs to using our own custom one). This struct has the
advantage of supporting ranges, massively reducing traffic over
the wire for Podman commands using them (for example, the
`podman run -p 5000-6000` command will now send only one struct
instead of 1000). This struct also allows us to easily validate
which ports are in use, and which are not, which is necessary for
--expose.
Once we have parsed the ports from the new struct, we can produce
an accurate map including all currently requested ports, and use
that to determine what ports need to be exposed (some requested
exposed ports may already be included in a mapping from --publish
and will be ignored) and what open ports on the host we can map
them to.

A surprisingly big change. A core problem was that `podman inspect`
allows for passing containers AND images with the default `--type=all`.
This only worked partially as the data was processed in isolation which
caused various issues (e.g., two separate outputs instead of one) but it
also caused issues regarding error handling.
