Proposed Changes

ApplyPolicyConfig struct now takes a slice of policies instead of a single policy. We are then changing the way Kyverno engine is invoked in the CLI. Now on a single resource we apply all mutate policies, then verifyImage then validate then generate policies.

Proof Manifests

This PR contains mostly refactoring, all the unit test cases in apply_command_test.go and common_test.go pass
