      Description

      Now that IMPALA-7467 is fixed, ExecQueryFInstance() can utilize the async RPC capabilities of KRPC instead of relying on the half-baked way of using ExecEnv::exec_rpc_thread_pool_ to start query fragment instances. We already have a reactor thread pool in KRPC to handle sending client RPCs asynchronously. Also various tasks under IMPALA-5486 can also benefit from making ExecQueryFInstance() asynchronous so the RPCs can be cancelled.
