> During a datanode startup, we current pass dfs.container.ratis.conf so that 
> the datanode is bound to a particular Ratis cluster.
> In this JIRA, we change Datanode that the datanode is no longer bound to any 
> Ratis cluster during startup. We use the Ratis reinitialize request 
> (RATIS-86) to set up a Ratis cluster later on.
