bad7a3fbbd kubeadm/*/phases/init/certs,kubeconfig: add "kubernetes-version" flag 
If empty "--kubernetes-version" is given (as it's not configurable now)
k8s.io/kubernetes/cmd/kubeadm/app/util/version.go.KubernetesReleaseVersion
will fetch the version from the internet.

But, this can fail:

% kubeadm init phase certs ca --cert-dir ...
unable to fetch file. URL: "https://dl.k8s.io/release/stable-1.txt", status: 502 Bad Gateway
failed to run commands: exit status 1

Can happen to other commands:

% kubeadm init phase kubeconfig controller-manager ...
% kubeadm init phase kubeconfig scheduler ...

This make "--kubernetes-version" configurable, so users can enable offline mode.

25668531f7 kubeadm: run MemberAdd/Remove for etcd clients with exp-backoff retry 
When adding a new etcd member the etcd cluster can enter a state
of vote, where any new members added at the exact same time will
fail with an error right away.

Implement exponential backoff retry around the MemberAdd call.

This solves a kubeadm problem when concurrently joining
control-plane nodes with stacked etcd members.

From experiment, a few retries with milliseconds apart are
sufficient to achieve the concurrent join of a 3xCP cluster.

Apply the same backoff to MemberRemove in case the concurrent
removal of members fails for similar reasons.

8739ade3fa kubelet: add CNI cache dir option and plumb through to CNI and kubenet 
libcni 0.7.0 caches ADD operation results and allows the runtime to
retrieve these from the cache. In case the user wants a different
cache directory than the defaul, plumb that through like we do
for --cni-bin-dir and --cni-conf-dir.

668d69799a kubeadm: prevent PSP blocking of upgrade image prepull 
If the cluster has a PSP that blocks Pods from running as root
the DS that handles upgrade prepull will fail to create its Pods.

Workaround that by adding a PodSecurityContext with RunAsUser=999.

cb56f91cc6 kubeadm: don't use the Docker SDK in util/system/docker_validator* 
Instead of creating a Docker client and fetching an Info object
from the docker enpoint, call the "docker info" command
and populate a local dockerInfo struct from JSON output.

Also
- add unit tests.
- update import boss and bazel.

This change affects "test/e2e_node/e2e_node_suite_test.go"
as it consumes this Docker validator by calling
"system.ValidateSpec()".
