Here are some alternatives I have considered before:

1. Split reposetup from hg.repository() and add the flag elsewhere,
which is a non-trivial, may be a breaking change.

2. Use a separate command marked as "norepo" for chgserver ("norepo"
will still load repo config), but then we need some hack to silence
"warning: --repository ignored".

3. Make chgserver a standalone hg binary that does not start from hg.py.
This may only make sense if we have done enough refactoring to make it
easy to implement dispatch.py-like logic.

I think it's okay to add it here for now since this change looks safer
then alternatives and the alternatives are not 100% ideal either, plus
we already have 'wirepeersetupfuncs'.

Ideally we may do enough refactoring and then can come back to see if we
have better place for this one and 'wirepeersetupfuncs'.
