Perform remote ostree pull during local-based ostree install

For Redfish-based subcloud installs which use a local ostree repo as the
basis of their install, we perform a secondary ostree pull from the
system controller. This will pull any ostree commits which have been
applied (via patch) since the local ostree repo was created.

Note that this also requires syncing of the patch metadata via
/opt/patching. This step is done via the install ansible playbook.

Test Plan:

PASS:
- Simulate a local ostree-based install during a sushy subcloud add in
  libvirt. Verify that a remote ostree pull retrieves any patch commits
  from the system controller. This is done by manipulating ostree repo
  contents on the system controller during the miniboot.cfg kicktart.

PASS:
- Prestage a subcloud from a non-patched system controller.
  Prestaged ostree_repo is stored on platform-backup partition.
  Patch the system controller. Add the prestaged subcloud.
  Verify that the subcloud boots and that the patched ostree commit
  is transferred to the subcloud during the miniboot.cfg kickstart.
