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.

we need to alter the return error message when a GET (inspect) is performed on an image using the compatibility layer. docker-py bindings look for a initial capped error message.

due to a lack of "locking" on cni operations, we could get ourselves in trouble when doing rapid creation or removal of networks. added a simple file lock to deal with the collision and because it is not considered a performent path, use of the file lock should be ok. if proven otherwise in the future, some generic shared memory lock should be implemented for libpod and also used here.
moved pkog/network to libpod/network because libpod is now being pulled into the package and it has therefore lost its generic nature. this will make it easier to absorb into libpod as we try to make the network closer to core operations.

Make Podman pod operations that do not involve starting
containers (which needs to be done in a specific order) use the
same parallel operation code we use to make `podman stop` on
large numbers of containers fast. We were previously stopping
containers in a pod serially, which could take up to the timeout
(default 15 seconds) for each container - stopping 100 containers
that do not respond to SIGTERM would take 25 minutes.
To do this, refactor the parallel operation code a bit to remove
its dependency on libpod (damn circular import restrictions...)
and use parallel functions that just re-use the standard
container API operations - maximizes code reuse (previously each
pod handler had a separate implementation of the container
function it performed).
This is a bit of a palate cleanser after fighting CI for two
days - nice to be able to return to a land of sanity.

Fix the remote client to untag all tags of the specified image.
Instead of querying the image on the client side, support the
case where both, repo and tag, are empty and remove all tags.
Reuse the ABI implementation where possible. In retrospective,
the libpod untag endpoint should support a slice of strings to
batch remove tags rather than reaching out for each tag individually.
Enable the skipped test.

In podman containers rm and podman images rm, the commands
exit with error code 1 if the object does not exists.
This PR implements similar functionality to volumes, networks, and Pods.
Similarly if volumes or Networks are in use by other containers, and return
exit code 2.

in the compatibility layer, creating a volume with a name that already does not result in an error. instead a 201 response with the existing volume's information is returned. while it seems like a bug on the part of docker and they agree, no attempt has been made to fix it in five years.

Currently the --pull missing|always|never is ignored
This PR implements this for local API. For remote we
need to default to pullpolicy specified in the containers.conf
file.
Also fixed an issue when images were matching other images names
based on prefix, causing images to always be pulled.
I had named an image myfedora and when ever I pulled fedora, the system
thought that it there were two images named fedora since it was checking
for the name fedora as well as the prefix fedora. I changed it to check
for fedora and the prefix /fedora, to prefent failures like I had.
