Add an optional --storage flag to the following commands:
- images delete
- info
- mount
- verify
- version
If specified, the command will only look at the specified storage
(ostree/docker) for the image to perform the action. If not
specified, the command will look through both ostree/docker for
the image (as it was before). However, if the storage is not
specified and the image exists in both ostree and docker, the
command will error and prompt the user to specify. Image inspection
also no longer forces the user to delete/rename one or the other.
This is meant to address the duplicate naming issue (where a user
can have an image in both ostree and docker with the same name).

Ostree already has functionality to extract images as non-root user. This involves changing OSTree's checkout mode to USER (only if the image's repo was created with BARE_USER mode).
Atomic will then ignore calls to mount_path since there is no need to run the mount systemcall since ostree checkout already takes care of thata.
Also added changes to allow atomic to unmount an image previously mounted by non-root user. This involves a patch to atomic mount to change permissions of the image once mounted. It then removes symbolic links before removing all the subdirectories in the specified mount directory.
