Replace the unnecessary use of InitConfiguration in images.go with
ClusterConfiguration. This changes the interfaces of the following functions:
- GetKubeControlPlaneImage
- GetEtcdImage
- GetAllImages
Signed-off-by: Rostislav M. Georgiev <rostislavg@vmware.com>
Until now, kube-proxy image was handled in two separate places:
- In images.go along with the pre-pull code and without having the image
override capabilities (via UnifiedControlPlaneImage)
- In the kube-proxy manifest, where image override was possible.
This duplicates the kube-proxy image logic and makes it prone to errors.
Therefore, this change aims to deduplicate it and make it more straightforward.
This is achieved in the following ways:
- GetKubeControlPlaneImage is used for kube-proxy image fetching, thus allowing
for the image to be overriden by UnifiedControlPlaneImage.
- Remove duplicated logic from the manifest and use GetKubeControlPlaneImage to
generate the image for the manifest.
Additionally, GetKubeControlPlaneImageNoOverride is removed as the only use case
for the function is now invalid.

kube-proxy should be able to run on all nodes, independent
on the taint of such nodes.
This restriction was previously removed in bb28449e31 but
then was brought back in d1949261ab.
Also, annotate with:
scheduler.alpha.kubernetes.io/critical-pod: ""
and add a class in the template spec:
priorityClassName: system-node-critical

Update kubeadm's minimum supported Kubernetes in v1.11.x to 1.10
**What this PR does / why we need it**:
This PR does,
* Restricts supported Kubernetes version in 1.11 cycle;
* Removes useless v190-specific variables, since the minimum version is v1.10;
* Bumps etcd version based on k8s version to 1.10.X => 3.1.12, 1.11.X => 3.2.18, 1.12.X => 3.2.18;

kubeadm: Make kube-proxy tolerate all taints
**What this PR does / why we need it**:
As a essential core component, kube-proxy should generally run on all
nodes even if the cluster operator taints nodes for special purposes.

Update bazelbuild/rules_go, kubernetes/repo-infra, and gazelle dependencies
**What this PR does / why we need it**: updates our bazelbuild/rules_go dependency in order to bump everything to go1.9.4. I'm separating this effort into two separate PRs, since updating rules_go requires a large cleanup, removing an attribute from most build rules.

Kubeadm: clean up MarshalToYamlForCodecs
Proxy will use PrintBytesWithLinePrefix to indent.

This removed the function MarshalToYamlForCodecsWithShift() and the proxy
code will use PrintBytesWithLinePrefix() to shift over the yaml lines.

This moves plugin/pkg/scheduler to pkg/scheduler and
plugin/cmd/kube-scheduler to cmd/kube-scheduler.
Bulk of the work was done with gomvpkg, except for kube-scheduler main
package.

pkg/api: extract Scheme/Registry/Codecs into pkg/api/legacyscheme
This serves as
- a preparation for the pkg/api->pkg/apis/core move
- and makes the dependency to the scheme explicit when vizualizing
left depenncies.
The later helps with our our efforts to split up the monolithic repo
into self-contained sub-repos, e.g. for kubectl, controller-manager
and kube-apiserver in the future.

bazel: build/test almost everything
**What this PR does / why we need it**: Miscellaneous cleanups and bug fixes. The main motivating idea here was to make `bazel build //...` and `bazel test //...` mostly work. (There's a few reasons these still don't work, but we're a lot closer.)

Previously, kubeadm would use <ip>:<port> to construct a master
endpoint. This works fine for IPv4 addresses, but not for IPv6.
IPv6 requires the ip to be encased in brackets when being joined
to a port with a colon.
This patch updates kubeadm to support wrapping a v6 address with
[] to form the master endpoint url. Since this functionality is
needed in multiple areas, a dedicated util function was created.
Fixes: https://github.com/kubernetes/kubernetes/issues/48227
