Remove Service Principal Post Deployment

[tayganr]

Current State

• The service principal which is created at the beginning of the template remains post deployment.

Limitation

• User needs to manually clean-up/remove service principal (Azure Portal > Azure Active Directory > App Registrations).
• This was previously included in the tail end of the preDeploymentScript but testing seemed to indicate that the service principal was being removed before the data plane operations had complete, causing the overall deployment to fail.

Request

• Update the script to remove the service principal once the data plane operations are complete.
