Reason for Change:

Previous fix didn't cover all cases. In the following issues reported by customer, even the Pod-Max-Pids is set to -1 when the SupportPodPidsLimit is not set, but that value in the agent pool profile is still original default value 100 which may still cause issue. Though we didn't observed issue for MasterProfile right now, we believe in some heavy load cluster, it may have potential issue with those CCP pods on master node. That's the reason why we should extend the fix#1508 to MasterProfile and AgentPoolProfile.

Issue Fixed:

Fixes #1270

Requirements:
