Updated missing documentation for cluster remap command (#1079)

The `cluster-remap` and `revert-cluster-remap` commands have been added
to the project's open-source library to assist administrators in
managing their clusters' UC settings. The `cluster-remap` command allows
users to remap their clusters to UC-enabled ones by providing a
comma-separated list of cluster IDs. It updates the specified clusters
to UC-enabled and stores a backup of the existing cluster configuration
in a JSON file. This backup can be used to revert the cluster remapping
if necessary using the `revert-cluster-remap` command. This command
iterates through the list of clusters from the backup folder and reverts
the cluster configurations to their original state. These commands
provide administrators with the ability to manage their clusters' UC
settings and revert any changes made to the cluster configurations if
necessary, ensuring the integrity and flexibility of their systems.

+
+This command will remap the cluster to uc enabled one.When we run this command it will list all the clusters 
+and its id's and asks to provide the cluster id's as comma separated value which has to be remapped, by default it will take all cluster ids.
+Once we provide the cluster id's it will update these clusters to UC enabled.Back up of the existing cluster 
+config will be stored in backup folder inside the installed location(backup/clusters/cluster_id.json) as a json file.This will help 
+to revert the cluster remapping.
