[Enhance] Add CI for turbo and enhance other tests

[WaberZhuang]

What this PR does / why we need it:
To enhance integration testing, I did the following three things:

• Add reproducing TurboOCI test case
• Use a local registry within workflow containers, and the registry is configured with a self-signed certificate so we can access it via HTTPS
• Add userspace-convertor E2E test case, it will push converted images to the local registry and run them

Which issue(s) this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged):
Fixes #

Please check the following list:

• Does the affected code have corresponding tests, e.g. unit test, E2E test?
• Does this change require a documentation update?
• Does this introduce breaking changes that would require an announcement or bumping the major version?
• Do all new files have an appropriate license header?
