Michael Ho d60eb192a9 IMPALA-6285: Don't print stack trace on RPC errors. ...

There is not much benefit in printing the stack trace when
Thrift RPC hits an error. As long as we print enough info about
the error and identify the caller, that should be sufficient.
In fact, it has been observed that stack crawl caused unnecessary
CPU spikes in the past. This change replaces Status() with
Status::Expected() in DoRpc(), RetryRpc(), RetryRpcRecv() and
Coordinator::BackendState::Exec() to avoid unnecessary stack crawls.

Testing done: private core build. Verified error strings with
test_rpc_timeout.py and test_rpc_exception.py
