Cinder had config options to customize the RPC topics on which the scheduler, volume and backup nodes listen. But this feature has been dysfunctional for quite a long time. This commit removed this feature. For more details: Refer the bug comments. DocImpact Change-Id: Ie76f070fe9a1222c209e8defd0d04fa7a7931b14 Closes-Bug: #1301888

1.3 - Dummy version bump to mark start of having cinder-backup service
