  - Merge "Add overrides and test jobs for UV images"
  - Add overrides and test jobs for UV images

    We build two sets of images in Loci.

    1) For legacy images we first build so called
       requirements image that contains all the necessary
       wheels and then we build all other project images
       using these wheels from the requirements image.
    2) Also recently we added another set of images
       that we build using the two stage Dockerfile.
       On the first stage we build venv using UV and
       then we just copy the venv as is to the project
       image.

    We are going to support two sets of images for two
    release cycles before we decide how to continue.
