fix: inconsistent json and yaml spanner configs

This tries to resolve inconsistent timeout/retries in different client
libraries.

Two major changes:
- Update *_grpc_service_config.json and *_gapic.yaml to make sure that they
  are consistent.
- Add missing ListDatabases config in spanner_admin_database_gapic.yaml.
