Make Pylint more flexible with a YAML-based config

See also: pytools#4 (closed)

This adds support for a YAML-based config file format for Pylint with a thin wrapper script that translates the YAML file into command line arguments.

This change also modifies prepare-and-run-pylint.sh to look for YAML configs. It looks for a .pylintrc.yml, and if it does not find it, it downloads the global config file from ci-support. It also supports local configurations via the file .pylintrc-local.yml.

@inducer: I think this addresses all the bullet point concerns you have in pytools#4 (closed). How do you feel about it? I think the YAML wrapper is a less annoying way of maintaining configurations than directly maintaining lists of command line arguments.

This looks lovely. And not the least bit overengineered. :P

Would merge if it weren't marked WIP.

Aka feel free to once you're happy with it.

I'm not merging yet because it would break the existing Pylint CIs.
