Review comment:
Since "LocatorClusterManagementService" is central to the
ClusterConfigurationService; will it be better to have the cms-dlock service
created in this class; and have helper method to lock and unlock. Assumption is
when the lock is requested the Locator Management service will be up and
running.

Review comment:
How about naming it as "updatesClusterConfiguration" (); they both are
same, just another name to consider, its left to you.

How about combining all of the if into an AND condition.
if (cmsDlockService == null && !(command instanceof GfshCommand) &&...)
