IPAM Deployment Resource Cleanup

[cocallaw]

The deployment of IPAM creates registrations in Azure AD and multiple Azure Resources depending on the deployment model. If the deployment fails due to missing prerequisites, permissions or capacity issues, users are left with a mix of resources and AAD resources that can be confusing to cleanup, especially if they have deployed more than once.

What would be the best option to provide cleanup of resources should the deployment fail?
Should the cleanup logic be contained in the Deploy.ps1 script or should a secondary script be utilized?
