Add Tempest rock

Implement tempest snap as a rock image for tempest-k8s operator

[gboutry]

The Rock seems okay, but have you tried coming up with a configuration for renovate using snapstore apis ? instead of having a cron job to rebuild the snap

I believe renovate can be configured using output from: https://api.snapcraft.io/v2/snaps/info/tempest?architecture=amd64 and custom rules

Thanks for the review. We are going to convert it to draft for now, we need to do some testing with the tempest-k8s charm first.

Tested and works for me with the tempest-k8s charm. Just one comment about adding comments to document design decisions, but otherwise good to go.

[samuelallan72]

as discussed in the syncup, would you mind adding an inline comment here to explain why the python plugin and python3-venv package are required?

@hemanthnakkina @gboutry We removed the workflow for rebuilding rock image when snap-tempest is updated, just to make the scope smaller for this PR. I'll appreciate your review again.
