az ad app permission add duplicate permissions

[jeevanions]

The Azure CLI command az ad app permission add command allows duplicate permission on subsequent runs. We use this command in a shell script, and it would be good to make the command check for the same permission before creating one.

Example CLI Command is given below

az ad app permission add --id <appId> --api 00000003-0000-0000-c000-000000000000 --api-permissions 5b567255-7703-4780-807c-7be8301ae99b=Role
