Add retries to catalogd RPCs. Previously, connection failures triggered
a retry, but failures on the actual RPC did not trigger a retry. This
change replaces all usages of ClientCache::DoRpc() in the
CatalogOpExecutor with ClientCache::DoRpcWithRetry(). This change moves
the connection retry loop to DoRpcWithRetry(), instead of relying on the
ClientCache to retry the connection.
This patch is based to IMPALA-8904, which adds similar functionality to
statestore RPCs.
Testing:
* Renamed test_statestore_rpc_errors.py to test_services_rpc_errors.py
and added new tests for catalogd RPC errors
* Added new tests to test_restart_services.py
* Ran core tests
