Fix kubeadm upgrade ignores HighAvailability feature gate
**What this PR does / why we need it**:
This PR fixes https://github.com/kubernetes/kubeadm/issues/731
**Which issue(s) this PR fixes**:
Fixes https://github.com/kubernetes/kubeadm/issues/731
**Special notes for your reviewer**:
The problem is a regression introduced by [#55952](https://github.com/kubernetes/kubernetes/pull/55952) which added a --feature-gates
flag to `kubeadm upgrade`, to be used for updating feature gates during the upgrade process (so it is update + upgrade).
The original implementation always override the actual feature gates with the flag value, even when the flag is not set; this PR fixes this behaviour making `kubeadm upgrade` considers the flag value only if set, otherwise actual feature gates will be preserved.
/cc @kubernetes/sig-cluster-lifecycle-pr-reviews @kubernetes/sig-cluster-lifecycle-bugs
**Release note**:
```release-note
Fixed#731 kubeadm upgrade ignores HighAvailability feature gate

allow higher burst for discovery
Discovery makes a lot of consecutive (maybe someday parallel) calls. One for every group and another for every version. Add a few CRDs and it's pretty easy to get to 50 calls.
This targets the burst on kubectl's discovery client only.

Don't log when error returned

**What this PR does / why we need it**:
When using `kubeadm init --apiserver-advertise-address=****, `apiserver-advertise-address` can only be ipv4 or ipv6 address, if people use domain name in this field, will not use it and silently get hostIP.

With CRI, kubelet no longer sets up networking for the pods. The
dockershim package is the rightful owner and the only user of the
newtork package. This change moves the package into dockershim to make
the distinction obvious, and untangles the codebase.
The`network/dns`is kept in the original package since it is only used by
kubelet.
The code was added to support rktnetes and non-CRI docker integrations.
These legacy integrations have already been removed from the codebase.
This change removes the compatibility code existing soley for the
legacy integrations.

OIDC required claims
**What this PR does / why we need it**:
Currently there is no mechanism for a user to specify claims in the OIDC authentication process that are required to be present in the ID Token with an expected value. This PR adds the required claims support for the OIDC authentication. It allows users to pass in a `--oidc-required-claims` flag, and key=value pairs in the API config, which will ensure that the specified `required claims` are checked against the ID Token claims.

Reimplement migrate-if-needed.sh in go
The `migrate-if-needed.sh` script was already partially implemented in go (see the attachlease and rollback sub-dirs), but was still unnecessarily difficult to understand and test. This closely reimplements the original logic but with improved code structure, error handling and testing.
Where possible, go code that was previously executed as separate binaries is now statically linked into a single 'migrate' go cobra CLI app, which is then thinly wrapped by`migrate-if-needed.sh`.
There are numerous additional improvements that need to be made, but will be submitted in future PRs. This PR is focused on achieving parity with the pre-existing functionality and introducing some much needed test coverage, in particular HA cluster upgrade test coverage.
It appears that the `attachlease` and `rollback` go binaries are no longer needed as standalones and so I have consolidated them into the new `migrate` go binary. Other than that, this change aims to be 100% backward compatible.
