* Removed the apostrophe from the Hadoop user guide menu pull down to be consistent with the crowbar user guide menu item.
* Added raise Errno::ECONNREFUSED, "CM - ERROR: Cannot create CM API resource" on cm-server connection failures in order to force a cm-api retry.
* Only set node[:clouderamanager][:cluster][:cm_api_configured] = true if cm-api executions succeeds. Force this value to false if the cm-server connection fails.
