Updated meta.yaml gen format; datafetcher and faultchecker tested and both work on Mac and Linux (faultchecker doesn't install pika when installing it for some reason)

Implemented parsing of setup.py files within a buildout recipe; next is to generate meta.yaml files for each setup file parsed

SSA-6324: tests pass when run locally; some fail in Docker container. Committing what I've got so as not to lose it after tearing my hair out for a day and a half.
