-----------------------------------------

Thanks for working on this [~shashikant]. The current patch looks good to me. Some comments as following.

1) Please correct the ASF license failure.
2) Lets also maintain the list of 1 node pipelines as well, so that multiple one node pipeline are not created on the same node.

> Currently, if a datanode is a part of 3 node Ratis pipeline, it cannot participate in a single node Ratis pipeline. This Jira aims to enable datanodes to become part of a a 3 node Ratis pipeline as well as single node Ratis pipeline. This is the first step in introducing multiRaft in Ozone.
