As part of revamped Package Overviews within Cloud RAD, we're adding links to REST / RPC documentation where it exists. For example, for google-cloud-apikeys, the REST documentation exists here: https://cloud.google.com/api-keys/docs/reference/rest and the RPC documentation exists here: https://cloud.google.com/api-keys/docs/reference/rpc.

Adding links to those pages within the .repo-metadata.json file at time of new client creation will help generate the updated documentation.

The REST/RPC documentation is currently generated in a process separate from the client library generation, hence coverage of whether the documentation exists is spotty and needs to be manually checked.
