Tracks the changes required for configuration DR.
configurations added:
DFS_REGION_ID("dfs.region.id") : the region id of current cluster

the primary cluster and mirror cluster

configurations modified:
The configurations in NAMENODE.NAMENODE_SPECIFIC_KEYS can be configured in
the following format to distinguish between clusters.
If a configuration with a region id as suffix cannot be found, the
configuration without region id as suffix will be used instead:
<configuration key>.<nameservice id>.<namenode id>.<region id>
