The v2 REST conrtoller have a LocatorClusterManagementService instance injected and created

As originally implemented, the controller is a noop. Inject a {ClusterManagementService}} into the controller and call it's create method.

The result of this implementation should be:

When: curl <cluster host>:7070/geode-management/v2 with a cache element with region name and type

Then: gfsh list regions should show that the region was created in the cluster
