Add an arg to ParseNodeIPArgument saying whether to allow dual-stack
IPs for external cloud providers. Update kubelet for the new API, but
always pass "false" for now.
The same code should be used to parse the command-line argument and
the annotation. Unfortunately, for compatiblity reasons, they have to
handle invalid inputs differently...
(It doesn't make sense to put this code in cloud-provider, since
ParseNodeIPArgument is used for the non-cloud-provider case too.)
Since Topology manager is graduating to GA, we remove
internal configuration variable names with `Experimental`
prefix.
There is no expected change in behavior, only trival
variable renaming.

Updating the required code and docs for SeccompDefault to go GA, which
now means that we enable the feature per default.

In fact, this actually uses pkg/util/node's GetHostname() but takes
the unit tests from cmd/kubeadm/app/util's private fork of that
function since they were more extensive. (Of course the fact that
kubeadm had a private fork of this function is a strong argument for
moving it to component-helpers.)
The --contention-profiling flag enables block profiling by calling
SetBlockProfileRate(). It, however does not call SetMutexProfileFraction
which enables mutex profiling.
Mutex profiling gives us information about lock contention whereas
block profiling on the other hand gives us information on gorotuines
being blocked on sync primitives.
Updating the docs to "block profiling" in order to make it more accurate.
Eventhough a block profile may reflect contention points on locks to some
extent, it also talks about other sources where goroutines may be blocked.

Dependencies need to be updated to use
github.com/container-orchestrated-devices/container-device-interface.
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.
This patch adds new Kubelet option topologyManagerPolicyOptions.
To introduce new TopologyManager options, first we need to introduce new
flag called `topology-manager-policy-options` to allow users to modify
behaviour of best-effort and restricted policies.

CPUManager is going GA, thus it makes little sense
to keep the names of the internal configuration
variables `Experimental*`.
Trivial rename only.
