Summary: This is here to support other arcanist/phabrication integration modules. Note: this adds a new package. I'm not sure what the packaging ramifications are exactly, but surely there are some as other extensions start to depend on this. Test Plan: integration test is provided: ``` $ ../../hg-crew/tests/run-tests.py -j8 .................................................... # Ran 52 tests, 0 skipped, 0 warned, 0 failed. ``` Reviewers: #sourcecontrol, ttung Subscribers: mjpieters Differential Revision: https://phabricator.fb.com/D3215615
