obmc-scripts: Add maintainers

maintainers is a python library and collection of scripts for
parsing and generating OpenBMC MAINTAINERS files. The culmination of the
effort is the `obmc-gerrit` git wrapper that automatically adds people
listed in the per-repository MAINTAINERS file as reviewers on changes
pushed to Gerrit.
