reviews.
* Equality when insertion order is different
* UnsortedList contents
* Not-Subset cases
* Clone coverage
Describe use cases (node IDs, HT siblings, etc)
Call out novelty (Linux CPU list parse/dump)
Describe future work (relax immutable, refactor to use 'set')
All usage of builder pattern is convertible to cpuset.New()
with the same or fewer lines of code.
Migrate Builder.Add to a private method of CPUSet, with a comment
that it is only intended for internal use to preserve immutable
propoerty of the exported interface.
This also removes 'require' library dependency, which avoids
non-standard library usage.
FilterNot is only used in this file, and is trivially converted to a
'filter' call site by inverting the predicate.
Filter is only used in this file, so don't export it.
In 'set', conversions to slice are done also, but with different names:
ToSliceNoSort() -> UnsortedList()
ToSlice() -> List()
Reimplement List() in terms of UnsortedList to save some duplication.
Removes exit/fatal from cpuset library.
Usage in podresources test was not necessary.
Library reference in cpu_manager_test was moved to a local function, and
converted to use e2e test framework error catching.
When kubelet starts a Pod that requires device resources, if the device
plug-in updates the device at the same time, it may cause kubelet to crash.

Dependencies need to be updated to use

It's not decided yet whether we will implement Topology support
for DRA or not. Not having any toppology-related code
will help to avoid wrong impression that DRA is used as a hint
provider for the Topology Manager.
The path module has a few different functions:
Clean, Split, Join, Ext, Dir, Base, IsAbs. These functions do not
take into account the OS-specific path separator, meaning that they
won't behave as intended on Windows.
For example, Dir is supposed to return all but the last element of the
path. For the path "C:\some\dir\somewhere", it is supposed to return
"C:\some\dir\", however, it returns ".".
Instead of these functions, the ones in filepath should be used instead.
CPUManager is going GA, thus it makes little sense
to keep the names of the internal configuration
variables `Experimental*`.
Trivial rename only.

With graduation of device plugins to GA in 1.26, the feature gate is
enabled by default so `devicePluginEnabled` field no longer needs to
be passed at the time of Container Manager creation.
In addition to that, we remove the `ManagerStub` as it is no longer
needed.
