1088f4fb44 DRA resourceslice controller: do DeepCopy for driver resources 
The reason for the previous behavior was unnecessary performance overhead that
occurs when the caller already provided a "fresh" copy and doesn't touch it
afterwards.

But this is something that DRA driver developers can easily get wrong, so it's
better to be safe than sorry.

67f0428769 DRA resourceslice controller: delay sync 
When deleting a bunch of slices, the delete events queue the pool while it is
being synced. It then got synced again immediately, while the deleted slices
were still being removed from the informer cache. The obsolete slice in the
cache caused the controller to delete it again, which fails with a "not
found". That error is ignored, but this still caused extra API calls.

Now syncing gets delayed with a configuration duration (default: 30 seconds) so
the informer cache is more likely to be up-to-date when the pool gets synced
again.

99cf2d8a2e DRA resource slice controller: add E2E test 
This test covers creating and deleting 100 large ResourceSlices. It is strict
about using the minimum number of calls.

The test also verifies that creating large slices works.

7473e643fa DRA resource slice controller: use MutationCache to avoid race 
This avoids the problem of creating an additional slice when the one from the
previous sync is not in the informer cache yet. It also avoids false
attempts to delete slices which were updated in the previous sync. Such
attempts would fail the ResourceVersion precondition check, but would
still cause work for the apiserver.

d94752ebc8 DRA resourceslice controller: use preconditions for Delete 
It's better to verify UID and ResourceVersion of the ResourceSlice that we want
to delete. If anything changed, the decision to remove it might not apply
anymore and we need to check again.

a6d180c7d3 DRA: validate set of devices in a pool before using the pool 
The ResourceSlice controller (theoretically) might end up creating too many
slices if it syncs again before its informer cache was updated. This could
cause the scheduler to allocate a device from a duplicated slice. They should
be identical, but its still better to fail and wait until the controller
removes the redundant slice.

26650371cc DRA resourceslice controller: support publishing multiple slices 
The driver determines what each slice is meant to look like. The controller
then ensures that only those slices exist. It reuses existing slices where the
set of devices, as identified by their names, is the same as in some desired
slice. Such slices get updated to match the desired state.

In other words, attributes and the order of devices can be changed by updating
an existing slice, but adding or removing a device is done by deleting and
re-creating slices.
