0449cef8fd Increase timeout for DRA kubelet plugin client 
The 10 second timeout was too low. Given that the retry loop for the
kubelet itself is 90s, increasing the timeout to half of this seems
reasonable. Ideally we would pull in the variable that sets the retry
timeout to 90s and then just set our local timeout to half of that.
Unfortunately, this is not exported, so we settle (for now with just
explicitly setting it to 45s.

f6431c6138 DRA: don't query claims from API server 
When a pod is force-deleted UnprepareResources fails to get a claim
from an API server.
PrepareResources should cache claim info required by the
UnprepareResources so that UnprepareResources would get it from
the cache instead of querying API server.

b57c7e2fe4 Add CDI devices to device plugin API 
This change adds CDI device IDs to the ContainerAllocateResponse in the
device plugin API. This allows a device plugin to specify CDI devices
by their unique fully-qualified CDI device names using the related field
in the CRI specification.

a30410d9ce LimitedSwap: Automatically configure swap limit for Burstable QoS Pods 
After this commit, when LimitedSwap is enabled,
containers would get swap acess limited with respect
the container memory request, total physical memory
on the node, and the swap size on the node.

Pods of Best-Effort / Guaranteed QoS classes don't get
to swap. In addition, container with memory requests
that are equal to their memory limits also don't get to
swap.

The swap limitation is calculated in the following way:
1. Calculate the container's memory proportionate to the node's memory:
- Divide the container's memory request by the total node's physical memory.
  Let's call this value ContainerMemoryProportion.

2. Multiply the container memory proportion by the available
swap memory for Pods:
Meaning: ContainerMemoryProportion * TotalPodsSwapAvailable.

e4da568f33 Make kuberuntime unit tests environment independent + support cgroup v2 
Before this commit, to find out the current node's
cgroup version, a libcontainers function was used
directly. This way, cgroup version is hard to mock
and is dependant on the environment in which the unit
tests are being run.

After this commit, libcontainer's function is wrapped
within a variable function that can be re-assigned by
the tests. This way the test can easily mock the cgroup
version and become environment independant.

After this commit both cgroup versions v1 and v2
are being tested, no matter in which environment
it runs.
