"""Implement load scheduling across nodes, but grouping test by xdist_group mark.
This distributes the tests collected across all nodes so each test is run
just once. All nodes collect and submit the list of tests and when all
collections are received it is verified they are identical collections.
Then the collection gets divided up in work units, grouped by group mark
(If there is no group mark, it is itself a group.), and those work units
et submitted to nodes. Whenever a node finishes an item, it calls
``.mark_test_complete()`` which will trigger the scheduler to assign more
work units if the number of pending tests for the node falls below a low-watermark.
When created, ``numnodes`` defines how many nodes are expected to submit a
collection. This is used to know when all nodes have finished collection.
This class behaves very much like LoadScopeScheduling,
but with a itself or group(by marked) scope.
This class behaves very much like LoadScopeScheduling, but it groups tests by xdist_group mark
