It is interesting and I like the idea of some support but we are not a github
hosted project so workflows will not work for us. Plus at the moment the repos I
am interested in need to be converted to yapf for any support like this to work.
The yapf changes are not too bad, the pylint changes, which are worth doing,
take a lot longer.

I am running `yapf -i myfile.py` before I create the commit. This way I check
the changes as part of a review before creating the commit.

Could the precommit hook simply stop the commit and force you to run yapf if
there is a required change? Would this require you have yapf installed?
