Task: update Resourcegroup controller to catch and handle "LocationNotAvailableForResourceGroup"

[jananivMS]

Now that we have enabled the operator to work on multiple cloud environments, there are certain locations that do not work for a particular cloud environment. Ran into this error when trying to create a RG in a location not available for the current Cloud env.

To Reproduce
Steps to reproduce the behavior:

1. Update location in RG yaml to "chinanorth"
2. Try creating that using the operator (with the AzurePublicCloud environment which is our default)

Expected behavior
The operator should handle this error and end reconciliation with a failed reconcile.
However, the operator reports an error which results in requeuing of the operator. for an error that is unrecoverable.
