Added the chainsaw tests for kyverno 1.10 release

[nsathyaseelan]

• The Chainsaw test has been incorporated for the default curated policies of Nirmata Kyverno, and the existing KUTTL test suite has been eliminated.

• These Chainsaw tests are designed to execute with n4k 1.10 Nirmata Kyverno instances across all supported Kubernetes versions.

• Each Chainsaw test is responsible for validating the following policy aspects:

  • Creating the policy and verifying its status
  • Creating the remediate/mutate policy and checking its status (if applicable)
  • Generating a resource in the presence of the mutate policy
  • Verifying that the report does not contain any error or fail summaries
  • Removing the remediate policy
  • Transitioning the policy from Audit to Enforce mode
  • Creating a resource that adheres to the policy rule and confirming its successful creation
  • Attempting to create a resource that violates the policy and confirming that the resource creation is blocked.
