3. package-tarballs - (NEW) To package tarballs with a docker dependency
'release-in-a-container' is currently only for testing and is not slated to
be used, but may be useful for testing in some scenarios.
'cross-in-a-container' is meant to be run from the kube-cross image alone.
'package-tarballs' is a companion target that runs from a docker image
to package up the tarballs and images (from cross-in-a-container) for a release.

Cpu Manager - make CoreID's platform unique
**What this PR does / why we need it**:
Cpu Manager uses topology from cAdvisor(`/proc/cpuinfo`) where coreID's are socket unique - not platform unique - this causes problems on multi-socket platforms.
All code assumes unique coreID's (on platform) - `Discovery` function has been changed to assign CoreID as the lowest cpuID from all cpus belonging to the same core. This can be expressed as:
`CoreID=min(cpuID's on the same core)`
Since cpuID's are platform unique - above gives us guarantee that CoreID's will also be platform unique.

Move initializer plugin to the generic apiserver
* Moves `k8s.io/kuberentes/plugin/pkg/admission/initialization` to `k8s.io/apiserver/pkg/admission/plugin/initialization`
* Moves `k8s.io/kubernetes/pkg/kubeapiserver/admission/configuration` to `k8s.io/apiserver/pkg/admission/configuration`
* The initializer plugin used to depend on `k8s.io/kubernetes` because it does a type assertion of `api.Pod`. It tries to skip mirror pod. I converted that code to use the generic accessor pattern.

Make unnecessary hpa public funcs private
**What this PR does / why we need it**:
Previously
`pkg.controller.podautoscaler.UnsafeConvertToVersion` was
exported. However, it was never used outside of the `podautoscaler`
package. Make it private to prevent confusion.
Additionally, move the two private functions in `horizontal.go` to be
with the other private functions at the bottom of the file - imho its
more readable than having them directly at the top of the file, before
the public type and function definitions.
**Release note**:

Retry when checking Azure storage account readiness
**What this PR does / why we need it**: When the Azure cloud provider ensures that a default storage container exists, if the storage account exists but is still provisioning, it exits without retrying. This is a bug as the code is wrapped in a backoff policy but never signals the policy to retry. This PR fixes this behaviour by returning values which allow the backoff policy to operate.
**Which issue this PR fixes**: fixes#53052

**What this PR does / why we need it**:

Add launching Cluster Autoscaler in Kubemark
**What this PR does / why we need it**:
Allows to launch Cluster Autoscaler in Kubemark.
To do it, set ENABLE_KUBEMARK_CLUSTER_AUTOSCALER flag to true. This currently only works with one nodegroup, for which you can specify minimum and maximum number of nodes and name. (KUBEMARK_AUTOSCALER_MIN_NODES, KUBEMARK_AUTOSCALER_MAX_NODES, KUBEMARK_AUTOSCALER_MIG_NAME).
Is is important to note that NUM_NODES has a different meaning when launching Cluster Autoscaler - we always start with only one node, but NUM_NODES is used to calculate the size of Kubemark master and addon components.
There are no changes to the current setup if ENABLE_KUBEMARK_CLUSTER_AUTOSCALER is set to false.
**Release note**:
