When an images does not exist just return `False` instead of
raising a RuntimeError. If anything else goes wrong (unknown
output or hash mismatch) keep the RuntimeError as this is an
unexpected exception.
The source implementation used `subprocess.run()` argument
`capture_output`, which was added in Python 3.7. Since the minimum
supported Python version for osbuild on RHEL-8 is 3.6, the stage fails
with TypeError.

This source checks for the existence of a local container in the host's
containers-storage. The source first reads the host's
`/etc/containers/storage.conf` file for the storage config and then
checks if the user has imported the desired container into the local
store.
Unlike the org.osbuild.containers stource, the
org.osbuild.containers-storage source doesn't need any extra data other
than the image ID. The ID is all that is used to retrieve the
container. The location and other information regarding the storage are
read from the host configuration and are not encoded in the manifest
There's no need to use the name to resolve it like we do in other
sources because containers in the local storage can be directly
referenced by their image id (config digest).
Other data such as the name of the container will only be relevant in
the stage that will use the container as input.
The source items are objects instead of simple strings of checksums
because we might, in the future, want to add specific options for each
source.
The content_type for this source is `containers-storage`, which defines
the location in the store where the source will bind mount the host's
container storage for stages to read. We make this different from the
containers content because it will be treated differently enough to need
a separate input type.
