pytest_handlecrashitem faults with NotImplementedError when using the loadgroup test distribution algorithm

[hb2638]

I'm using xdist with the --dist loadgroup command line option and the reruns are not working for crashed nodes because xdist's LoadScopeScheduling.mark_test_pending for throws a NotImplementedError error @ https://github.com/pytest-dev/pytest-xdist/blob/master/src/xdist/scheduler/loadscope.py#L244

Thank you for your PR. I do not know anything about the loadgroup test distribution algorithm.
So a PR is welcome to fix this issue.
