[dutt0]

Overview/Summary

This pull request introduces additional resource-based logic while determining the compliance status.

This PR fixes/adds/changes/removes

1. Added two more policy checks ("Storage accounts should restrict network access" and "Secure transfer to storage accounts should be enabled") in the required PBMM policy
2. Added additional resource-based logic while determining the compliance status. This change not only checks 'PBMM policy applied', But also finds the number of non-compliant resource(s) for any required policies and determines the compliance status of the resource based on non-compliant resources found.

Breaking Changes

None. However, users' compliance status may change.
