v181

NOTABLE NEW FEATURE:
Confab will not insert consul.encrypt_keys into consul's keyring if they have not changed. Particularly in large deployments, the key insertion can take several minutes (see v179, where the timeout for this was made configurable as confab.timeout_in_seconds). Now you should only see issues with timeouts or full disks leading to the message X/Y nodes reported success in logs when you are intentionally rotating the encrypt keys, in which case, you will still need to redeploy with a longer timeout or find the root cause of the issue.
