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.

Add a new "image" mount type to `--mount`. The source of the mount is
the name or ID of an image. The destination is the path inside the
container. Image mounts further support an optional `rw,readwrite`
parameter which if set to "true" will yield the mount writable inside
the container. Note that no changes are propagated to the image mount
on the host (which in any case is read only).
Mounts are overlay mounts. To support read-only overlay mounts, vendor

podman inspect only had the capabilities to inspect containers and images. if a user wanted to inspect a pod, volume, or network, they would have to use `podman network inspect`, `podman pod inspect` etc. Docker's cli allowed users to inspect both volumes and networks using regular inspect, so this commit gives the user the functionality
If the inspect type is not specified using --type, the order of inspection is:
containers
images
volumes
networks
pods
meaning if container that has the same name as an image, podman inspect would return the container inspect.
To avoid duplicate code, podman network inspect and podman volume inspect now use the inspect package as well. Podman pod inspect does not because podman pod inspect returns a single json object while podman inspect can return multiple)

External containers are containers created outside of Podman.
For example Buildah and CRI-O Containers.
$ buildah from alpine
alpine-working-container
$ buildah run alpine-working-container touch /test
$ podman container exists --external alpine-working-container
$ podman container diff alpine-working-container
C /etc
A /test
Added --external flag to refer to external containers, rather then --storage.
Added --external for podman container exists and modified podman ps to use
--external rather then --storage. It was felt that --storage would confuse
the user into thinking about changing the storage driver or options.
--storage is still supported through the use of aliases.
Finally podman contianer diff, does not require the --external flag, since it
there is little change of users making the mistake, and would just be a pain
for the user to remember the flag.
podman container exists --external is required because it could fool scripts
that rely on the existance of a Podman container, and there is a potential
for a partial deletion of a container, which could mess up existing users.

Current these commands only check if a container exists in libpod. With
this fix, the commands will also check if they are in containers/storage.
This allows users to look at differences within a buildah or CRI-O container.
Currently buildah diff does not exists, so this helps out in that situation
as well as in CRI-O since the cri does not implement a diff command.

Currenly if a user specifies the name or ID of an external storage
container, we report an error to them.

podman rm working-container-2
Error: no container with name or ID working-container-2 found: no such container
Since the user specified the correct name and the container is in storage we
force them to specify --storage to remove it. This is a bad experience for the
user.
This change will just remove the container from storage. If the container
is known by libpod, it will remove the container from libpod as well.
The podman rm --storage option has been deprecated, and removed from docs.
Also cleaned documented options that are not available to podman-remote.

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.
