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.

Clean up the network plugin code

backward compatibility with non-CRI runtimes, which are now removed from the
codebase.

validate AdvertiseAddress in kubeadm init and other case
**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.
Add a warning in this case.

**Release note**:

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.
