Prevent Kubelet from incorrectly interpreting "not yet started" pods as "ready to terminate pods" by unifying responsibility for pod lifecycle into pod worker
should mark volume mount in actual state even if volume expansion fails so that
reconciler can tear down the volume when needed. To avoid pods start
using it, mark volume as uncertain instead of mounted.
Will add unit test after the logic is reviewed.

Add e2e tests to cover the basic flows for the `full-pcpus-only` option:
negative flow to ensure rejection with proper error message, and
positive flow to verify the actual cpu allocation.

Consume in the static policy the cpu manager policy options from
the cpumanager instance.
Validate in the none policy if any option is given, and fail if so -
this is almost surely a configuration mistake.
Add new cpumanager.Options type to hold the options and translate from
user arguments to flags.

Introduce a new `admission` subpackage to factor out the responsability
to create `PodAdmitResult` objects. This enables resource manager
to report specific errors in Allocate() and to bubble up them
in the relevant fields of the `PodAdmitResult`.
To demonstrate the approach we refactor TopologyAffinityError as a
proper error.

The CPUManagerPolicyOptions received from the kubelet config/command line args
is propogated to the Container Manager.
We defer the consumption of the options to a later patch(set).

In this patch we enhance the kubelet configuration to support
cpuManagerPolicyOptions.
In order to introduce SMT-awareness in CPU Manager, we introduce a
new flag in Kubelet to allow the user to specify an additional flag
called `cpumanager-policy-options` to allow the user to modify the
behaviour of static policy to strictly guarantee allocation of whole
core.
