Add tests for trustee-operator

[bpradipt]

At least the following initial tests will be needed

• operator install and uninstall
• Trustee CRD creation, deletion
• secret release
• policy check (deny secret release due to policy deny)
• policy check (allow secret release due to policy allow)
• Update config, secret or policy via modifying the related K8s resources and verifying the update is reflected in the Trustee components
• scaling trustee pods and verifying secret release, policy checks, config updatesetc

Hello @bpradipt ... when referring to tests ... do you mean a GH action to perform the different proposals?

In https://github.com/latchset/tang-operator (https://github.com/latchset/tang-operator/blob/main/.github/workflows/deploy.yaml) we had some tests where the operator was installed and uninstalled through operator-sdk ... is this the proposal?

@sarroutbi right. A basic test framework based on kuttl is added as part of GH action.
