@jojochuang , thanks a lot for working on this!

This conf has two purposes:

  1. wait time between two subsequent AppendEntries, and
  2. set to waitForReady in GrpcLogAppender (for the sleep waiting a gRPC stream to ready).

For (1), zero is allowed. For (2), zero becomes 1ms.

Do you think that the usage in (2) is problematic? If yes, we may use a different conf.
