Subject: [PATCH] Setup necessary mounts for to-release deployment

In order to start a GA release deployment, mounts to drbd file
systems should be created to alternate ostree deployment branch
(i.e, /sysroot/ostree/<1|2>). This commit creates a yaml file to
be used by apt-ostree to do the mounts.

Test Plan:
Mounts created with success
Pkg build with success

Story: 2010676
Task: 48829
