configitems: use codemod script to register coreconfigitems

This is the result of running:

  contrib/codemod/codemod_configitems.py mercurial/**/*.py

Plus 2 manual fixes (to make test pass) according to the warning printed by
the script:

  [warn] mercurial/exchange.py: experimental.bundle2-output-capture: default needs manual removal
  [warn] mercurial/localrepo.py: experimental.hook-track-tags: default needs manual removal

The script cannot do that automatically because RedBaron cannot figure out
how to indent things [1].
