Epoch Write - is also called 'session write'. There will be two new methods added to the DistributedLogClientBuilder for building a DistributedLogClient.

These two new build methods are:

  1. enableSessionWrite(boolean) - The build method is to enable session write for the client built by this builder. By default, it will be false.
  2. enableExclusiveSession(boolean) - The build method is to enable exclusive session for the client built by this builder. By default, it will be false. This flag only take effects when #enableSessionWrite is set to true.
