Jonathan Hung commented on YARN-5948:
-------------------------------------

Attached a skeleton patch. Contains outline for MutableConfigurationManager and 
ConfigurationMutationPolicy. RMWebServices retrieves the configuration manager 
from the RMContext, calls MutableConfigurationManager#updateConfiguration, 
which will check against the configured policy. If it passes, the configuration 
manager will tell the configuration store to store the configuration change.

> Implement MutableConfigurationManager for handling storage into configuration 
> store

> The MutableConfigurationManager will take REST calls with desired client 
> configuration changes and call YarnConfigurationStore methods to store these 
> changes in the backing store.
