The node.status.addresses logic grew organically and with weird
semantics, this commit try to document existing semantics when
the kubelet uses an external cloud provider and recover the same
behavior existing pre-1.29.
The node.status.addresses can be populated by the kubelet at startup or
delegated to the external cloud provider.
If the --node-ip flag is set to an IP in the node, the kubelet will add
an annotation to the Node object that will be respected by the external
cloud providers, no new IP addresses will be added for the same address
type.
If the IP set in the --node-ip flag is `0.0.0.0` or `::`, the kubelet
will initialize the node with the default address of the corresponding
IP family of the unspecified address, and the cloud-provider will override
it later.
This implements a drop-in configuration directory for the kubelet
by introducing a "--config-dir" flag. Users can provide individual
kubelet config snippets in separate files, formatted similarly to
kubelet.conf. The kubelet will process the files in alphanumeric order,
appending configurations if subfield(s) doesn't exist, overwriting them if
they do, and handling lists by overwriting instead of merging.

kubelet option '--image-gc-low-threshold' description says it 'should not be larger than that of --image-gc-high-threshold'. But actually, it must less than '--image-gc-high-threshold', according to 02659772cb/pkg/kubelet/apis/config/validation/validation.go (L84)
Updating the required code and docs for SeccompDefault to go GA, which
now means that we enable the feature per default.

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.

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.

This change is to promote local storage capacity isolation feature to GA
At the same time, to allow rootless system disable this feature due to
unable to get root fs, this change introduced a new kubelet config
"localStorageCapacityIsolation". By default it is set to true. For
rootless systems, they can set this configuration to false to disable
the feature. Once it is set, user cannot set ephemeral-storage
request/limit because capacity and allocatable will not be set.
