Andy McCrae 57de3c8817 Check if changes have made before attempting a rebalance
Utilize the "ringbuilder.devs_changed" option to ensure that the ring
needs a rebalance. This will prevent unnecessary rebalances that cause
failures due to "min_part_hours" not being passed even though no changes
were required.

Additionally, we can now return a correct Ansible repsonse when the ring
has changed/rebalanced - and return "OK" when it hasn't returned at all.
