Subject: [PATCH] feat: add fips-operator-check task

Refers to CVP-4333. This task uses the check-payload tool to verify if
an operator bundle image is FIPS compliant.It utilizes Tekton stepAction
because the code will be reused for checking FBC fragments in the
fbc-validation check.

+# fips-operator-bundle-check task
+
+## Description:
+The fips-operator-bundle-check task uses the check-payload tool to verify if an operator bundle image is FIPS compliant.
+It only scans operator bundle images which either claim to be FIPS compliant by setting the `features.operators.openshift.io/fips-compliant`
+label to `"true"` on the bundle image or require one of `OpenShift Kubernetes Engine, OpenShift Platform Plus or OpenShift Container Platform`
+subscriptions to run the operator on an Openshift cluster.
