Description

Dynamic Configuraiton is very helpful that the operator can keep the JVM for regionserver or master running without restarting it.

With this feature, this task aims to extend the scope of on demend configuration to system coprocessors including REGION, USER REGION, REGIONSERVER, MASTER such that we could save time on rolling restart with a quicker update.
