feat: stepactions for secure push to OCI registry

[psturc]

JIRA

https://issues.redhat.com/browse/KFLUXDP-6

Description

This PR introduces 2 new stepactions:

• secure-push-oci, that scans the content of the specified directory, removes files that contain leaked information and pushes the directory content to the new/existing OCI artifact in quay.io, including the log from the leaktk CLI scan
• fail-if-any-step-failed - which purpose is to exit with non-zero code, if any of the steps executed as a part of the tekton Task exited with non-zero code. This is useful in Tasks, where we want to save artifacts that were produced by a step, where the error was purposely ignored (using error: continue field), but still want to fail the Task in the end, to give the user the correct job results
