This test performs a backup followed by a restore and compares
the restored data with the original data.
This code was previously in the freezer-api repo. It fits better
into the freezer repo because:
- It interacts mostly with freezer-scheduler
- The freezer devstack gate also includes the freezer-api so it is easier to run an end-to-end test
