Complete compare versions' workflow

[tellet-q]

A new workflow to compare 2 qdrant versions in 1 run:

1. check if there are images for the provided versions
2. if there is no image -> trigger image build workflow in qdrant repo and wait for image to appear in remote repo for up to 150 minutes
3. if image is ok -> proceed to benchmark execution
4. in the end compare results between to versions

Note: if the workflow triggered image build in the main repo and that triggered workflow is queued, then there is nothing we can do about it. If the triggered workflow took longer than 150 minutes the original job will fail
