Summary

This is a draft implementation of SDL and binary hardening test container used for kata-conformance-test pipeline. It's based on
the prototype in ankitapareek/kata-containerized-test-tool-v1, which is subject to change. Current plan is to:

1. Use this feature branch to start off SDL and binary hardening tests in kata-conformance-test pipeline.
2. Wait for test container upstream effort to complete
3. Downstream changes.
