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.

510ff67528 Use libcontainer's cgroup manager to update resources through systemd 
libcontainer's cgroup manager is version agnostic, and is agnostic
to whether systemd is used. This way if systemd is used, the cgroup
manager would be able to update resources properly so that if
the daemon would be restarted the changes would not be reverted.

7476f46d71 memorymanager: fix checkpoint file comparison 
For a resource within a group, such as memory,
we should validate the total `Free` and total `Reserved` size of the expected `machineState` and state restored from checkpoint file after kubelet start.
If total `Free` and total `Reserved` are equal, the restored state is valid.

The old comparison however was done by reflection.

There're times when the memory accounting is equals
but the allocations across the NUMA nodes are varies.

In such cases we still need to consider the states as equals.
