Control: 1.22 Ensure Custom Role is assigned for Administering Resource Locks

Description

Resource locking is a powerful protection mechanism that can prevent inadvertent modification/deletion of resources within Azure subscriptions/Resource Groups and is a recommended NIST configuration.

Given the resource lock functionality is outside of standard Role Based Access Control(RBAC), it would be prudent to create a resource lock administrator role to prevent inadvertent unlocking of resources.
