Add support for external container
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.

Display external containers that are not controlled by Podman but are stored in containers storage. These external containers are generally created via other container technology such as Buildah or CRI-O and may depend on the same container images that Podman is also using. External containers are denoted with either a 'buildah' or 'storage' in the COMMAND and STATUS column of the ps output. Only used with the --all option.
