The bot provisioning code was breaking due to pip.main not being
a function anymore. Also, I don't think we should pass the --quiet
option here. I felt it was good to have some visual information
about what deps were being installed, just in case if something
went wrong and there was a conflict, the user should be able to
see it.
This commit was originally from @fredfishgames, but it
needed a big rebase due to use letting it sit too long.
Also, we decided not to have shebangs at the top of test
files.
