From PR https://github.com/ManageIQ/manageiq/pull/12306: Modified update_serviceprovision_status to generate a notification for services in error. Message is 'Service Provision Error:' and the enhanced status message for the UI.
Verified on 5.8.0.4. When I modified the catalog item code to switch the state to error, I got this message: Service Provision Error: Server [EVM] Service [failtest2-20170317-084207] Step [pre5] Status [Error Processing Pre5] Message [Processing Pre5]
