Release Note

Forward port of HBASE-8805 and HBASE-8544 implemented by Gaurav Menghani in 89-fb. This improves operational efficiency in managing clusters that are serving production traffic. The idea is to have a central configuration which can manage notifying the configuration observers. The observers in turn should update their local state from the latest config. Minor caveats where configuration variables are corelated should be taken care of with additional care.

This patch is the server-part only. TODO is the activation, coming in a later issue.
