v179

NOTABLE NEW FEATURE:
The timeout for the overall job has been made configurable as confab.timeout_in_seconds. By observing the resolution of a production issue in Pivotal Web Services with Pivotal's Cloud Operations team we were able to determine that consul's gossip key insertion can take several minutes to complete in large scale deployments. This timeout allows consul_release to be tolerant of this. If you encounter the X/Y nodes reported success message in your logs when deploying consul, you should consider enlarging this timeout by a factor of 2.
