This is a check of ostree log output (commit and checksum) for determining if a patch is currently installed or not. The ostree commands are being moved to their own file. Additional ostree commands will be refactored in later commits. Test Plan: Verify controller-0 is Patch current when no patches installed. Verify controller-0 is Patch current when patches uploaded, but not applied. Verify controller-0 is NOT Patch current when a patch is applied.
