[green-dragon-migration] check in jenkins requirements file (#158)

* Add the requirements.txt file for jenkins CI agents. We separate this
from the global requirements.txt file since it's specific to green
dragon CI agents, and we don't want to inadvertently break any build
bots

This code has been tested on https://green.lab.llvm.org/
