There are two usages that I found and switched over
- hg ssl
- hg diff --since-last-arc-diff
The new phabricator_graphql_client.py file came mostly from
fbsource/fbcode/phabricator, but I had to modify it so it could use the lightweight url client instead of the (unavailable) thirdparty "requests" library
This requires the config changes in D6495153, and replaces D5339248
Maybe use docstring '''?
