This PR updates pytest-xdist from 3.5.0 to 3.6.0.

Changelog

3.6.0

===============================

Features
--------

- `1027 <https://github.com/pytest-dev/pytest-xdist/pull/1027>`_:``pytest-xdist`` workers now always execute the tests in the main thread.
Previously some tests might end up executing in a separate thread other than ``main`` in the workers, due to some internal `execnet`` details. This can cause problems specially with async frameworks where the event loop is running in the ``main`` thread (for example `620 <https://github.com/pytest-dev/pytest-xdist/issues/620>`__).

Bug Fixes
---------

- `1024 <https://github.com/pytest-dev/pytest-xdist/issues/1024>`_: Added proper handling of ``shouldstop`` (such as set by ``--max-fail``) and ``shouldfail`` conditions in workers.
Previously, a worker might have continued executing further tests before the controller could terminate the session.

- `1028 <https://github.com/pytest-dev/pytest-xdist/issues/1028>`_: Fixed compatibility issue between `looponfail` and editable installs.

- `620 <https://github.com/pytest-dev/pytest-xdist/issues/620>`_: Use the new ``main_thread_only`` ``execnet`` "execmodel" so that code which expects to only run in the main thread will now work as expected.

- `937 <https://github.com/pytest-dev/pytest-xdist/issues/937>`_: Fixed a bug where plugin would raise an incompatibility error with ``--pdb`` despite using ``-n0``.


Removals
--------

- `1053 <https://github.com/pytest-dev/pytest-xdist/issues/1053>`_: Dropped support for Python 3.7.

- `1057 <https://github.com/pytest-dev/pytest-xdist/issues/1057>`_: pytest>=7.0.0 is now required.

execnet>=2.1.0 is now required.


Trivial Changes
---------------

- `1020 <https://github.com/pytest-dev/pytest-xdist/issues/1020>`_: pytest-xdist's ``setup.py`` file is removed.

If you relied on this file, e.g. to install pytest using ``setup.py install``,
please see `Why you shouldn't invoke setup.py directly <https://blog.ganssle.io/articles/2021/10/setup-py-deprecated.html#summary>`_ for alternatives.

- `1057 <https://github.com/pytest-dev/pytest-xdist/issues/1057>`_: The internals of pytest-xdist are now fully typed. The typing is not exposed yet.

- `996 <https://github.com/pytest-dev/pytest-xdist/issues/996>`_: Adjusted license file format and content to ensure security scanners will identity the license.
