Add status command to display information the current deployment
of the OSTree repository when OSTree is deployed. This command
will not work from a non-OSTree deployed system.
The status command will display the current running branch,
in green. The current commit that is deployed and the Debian
version has been deployed.
Also update tox.ini and bindep.txt to support ostree.
Test Plan
PASSED Installed apt-ostree from git repo.
PASSED Run sudo apt-ostree compose create \
--base config/debian/bookworm \
--repo /repo debian/bookworm
PASSED Run "apt-ostree compose image --base config/debian/image \
--repo=/repo test"
PASSED Start VM.
