hi @eltorio,
if you haven't seen, CI is failing on this PR due to our policy for commit messages.
Usually I would suggest squashing messages, but this is not possible since more that one author has created those.

The easiest way to figure out what is the form of commit messages can be seen if you look at the git history.
Reasons how and most importantly why, can be seen here CONTRIBUTING

Unfortunately until this is resolved, we can't accept this PR.

PS. there one more open #608, almost with similar idea, but i guess this one is newer version ?

@eltorio any chance to work on the fix for the PR ?

Sure I need to check but I have a lot of work!
Since I made some other modifications I need to clean some things.
My fork continued its own life.
For example for our need it supports an annotation for enabling haproxy v2 protocol on tcproute
