Remove the application and version tags and replace "module" with "service".
The old tags have been deprecated for ages, and they cause warnings when we
do gradle deployment/staging.
TESTED:
Deployed to crash, everything still seemed to work to the extent that crash
can be expected to, service variations still happened, all services got
updated. Minimal risk to the other environments.
