This causes `upgrade-zulip-from-git`, as well as a no-option run of
`tools/build-release-tarball`, to produce a Zulip install running
Python 3, rather than Python 2. In particular this means that the
virtualenv we create, in which all application code runs, is Python 3.
One shebang line, on `zulip-ec2-configure-interfaces`, explicitly
keeps Python 2, and at least one external ops script, `wal-e`, also
still runs on Python 2. See discussion on the respective previous
commits that made those explicit. There may also be some other
third-party scripts we use, outside of this source tree and running
outside our virtualenv, that still run on Python 2.
We used to create endpoints with Client._register.
Now we now have explicit methods for the endpoints.
This allows us to add docstrings and stricter mypy annotations.
This fix also introduces a call_endpoint() method that avoids
the need for manually building urls with API_VERSTRING when you
know the URL pattern of the endpoint you want to hit (and when
the API doesn't have a convenient wrapper).
I fixed a bug with create_users where it now uses PUT instead
of POST.
I also removed client.export(), which was just broken.
I had to change recent-messages and zulip-export, which were
using client.do_api_query and Client._register.
Now it's easier to just call client.call_endpoint() for
situations where our API doesn't have convenient wrappers,
so that's what I did with those scripts.
