NIFI- 7255
Problem statement: In case the connection details of a node changes in a NiFi cluster and restarted, it might occur that the nodes with the old parameters remain in the "node list" of the nodes combined with the new version, thus duplicating the nodes. This results unreachable nodes and fail of replication in the end.
Solution proposal: both the node coordinator needs to clean up obsolete nodes, both the other nodes. This happens with comparing existing information from the local storage and incoming information from connection messages. As the id remains during these property changes that is considered as the key of comparison. Note: due to the equals method of the NodeIdentifier is based on only the id, that was not satisfying for check changes. I went with comparing getFullDescription as changing the equals would affect behaviour outside of this fix.
