include service name in revision for GCP cloud run

When creating new revisions in GCP Cloud Run, the name must include
the service name as prefix. The new format for the revision name
will follow the format: <service name>-rev-<commit hash>-<random-postfix>.

i.e.  hello-rev-c4685d4b9eefbbbf33055cd7ac9a62189b1e4476-6480ecbb
