-----------------------------------
[~szetszwo] Thanks for updating the patch! TestRaftAsyncExceptionWithGrpc fails
consistently with the patch.

> In OrderedAsync, the messages are sent asynchronously except for the first
> message. The first message is used to establish the connection.
> OrderedAsync will wait for the first message to complete before sending the
> following messages.
> Note that, when sending only two messages, the performance of sending the
> messages asynchronously is degenerated to sending them sequentially
> [~msingh] has discovered a case that can be optimized: an application may
> send two or more messages and the first message may take a long time to
> process. In this case, we may send a dummy lightweighted message establish
> the connection, and then send real messages.
