Switch Djblets's test suite to use pytest.

Reviewers

Historically, we've used nose as the test runner, with a custom test
runner script responsible for setting up a test run.

Unfortunately, nose 1.x hasn't been updated in a long while, and isn't
compatible with modern versions of Python 3. The forks also don't
support Python 3 very well. nose2 does, but is so different that it's
not a great option for us.

Instead, we're moving to pytest. This is a much more modern test
runner with a lot of interesting capabilities and a wide ecosystem of
plugins.

We now use this and define what little test setup we still need in
conftest.py, which is where we can define hooks for pytest to load.

We also use the pytest-django module, which is an official pytest
plugin for setting up a Django environment.

Developers can now run pytest directly to run the test suite. The old
./tests/runtests.py still works, but is deprecated, and merely wraps
pytests anyway.

Note that we still have a test runner we ship with Django that uses
nose. For now, this will continue to use nose, but we won't be using
it. We will need to evaluate a modernization or deprecation plan for
this.

Unit tests pass for all supported versions of Python.
