Description

There are some configurations for feature of dynamic resource configuration:
1. enable or not: if enable, then setting node resource in runtime through CLI/REST/JMX can be successful, else exceptions of "function not supported" will be thrown out. In future, we may support to enable this feature in partial nodes which has resource flexibility (like virtual nodes).
2. dynamic resource setting is persistent or not: it depends on users' scenario to see if the life cycle of setting in runtime should be kept after NM is down and restart.
