Compose RELEASE_SERVICE_VERSION into kubrick version

Summary:
version was increased to 1.1 "recently" and not so many changes have been done since them
so asserting the verison number is stuck in the past is a bit too much, but still having it move with
each new release is important for reproducibility of issues, etc. so compromise and append the relase service version at the end
