The rollback-soft feature was implemented in T5249.
It is time to think of renaming the features; we currently have rollback (with reboot) and rollback-soft (without rebooting)

• Proposed for renaming:

rollback => rollback-hard
rollback-soft => rollback

I.e. after refactoring:

rollback                  Rollback to a prior config revision (without reboot)
rollback-hard             Rollback to a prior config revision (requires reboot)

• Another idea would be to get rid of the old rollback which requires a reboot. As it is completely useless.

I think we can start with the first option.
