Make a mentor recruitment plan

1. make a recruitment plan for mentors:

• post to python-dev and other ML early (even now)
• explain clearly what a mentor should do and what results they can expect for the project
• As GSoC approaches send more mails (e.g. 6 months before, 3m, 1m, 2weeks)

We've had mediocre success with blind mentor recruitment, so we're not doing any this year -- mentors have to reach out to us to express interest. I'll probably revisit this in some future year if we get a volunteer who can help with this.
