wip: ruby provider

[nbw]

It's not quite there yet and breaks on Ruby install.

• use bundler to install gems
• what's the best way to detect a start file?

Notes

• Wish we used file scanners rather than reading the whole file
• The ergonomics of writing a plan are a bit complicated. might be hard to others to follow/adopt
