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.

The migration plan is as follows:
1. This CL, which adds the new "pubapi" service that serves the check API, WHOIS, and RDAP.
2a. Update our public facing sites to switch over to use the new service.
2b. (either order) Rewrite the check API to remove dependencies on flows.
3. ... eventually, once the frontend service is no longer being hit by this traffic, remove its handling of these public endpoints.
