As discussed in #3854, this PR proposes to change defaults values of draws and tune in pm.sample to 1000 and 2000 respectively -- both are currently at 500.
I also cleaned some PEP8 typos in sampling.py.
Happy to make deeper changes if needed, and thanks in advance for the reviews ✌️

I’m not sure I can think of any tests that are relevant here, but the change seems big enough that I think one of @fonnesbeck or @twiecki should chime in before merging.

LGTM. Will wait for Thomas, though.
