Now, defaults can be pointing to "stable" and users will always get
latest available stable build of Kubernetes via kubeadm.
There is no need anymore to hardcode version string inside kubeadm
binary.
It is also possible to use labels like "latest" or point to exact
branch: "stable-1.4"

Update kubeadm etcd to 3.0.13 in order to switch to the etcd3 storage format
ref: https://github.com/kubernetes/kubernetes/issues/35723
I think we should switch as soon as possible, but run it in etcd2 mode until the full etcd3 mode is stable

In future we might try to verify ports are actually exposed in firewalld
policy, but this can be quite complex. Instead lets just warn the user
if we see firewalld is running.
The kube etcd and discovery pods are set to unconfined_t in
order to avoid disabling selinux, but the correct type for
an unconfined container is spc_t. For more information, see

Check sysfs Type instead of Device
Some distribution uses "none" device to mount "sysfs" type, so kube-proxy needs to list mount points and check "types" instead of "device".
fixes#37183
```release-note
Change sysfs mountpoint tests from Device to Type to be able to find sysfs mountpoint on "none" device

Fields with omitempty tag should still be considered as optional
We've added an "+optional" tag while ago for optional fields. Before that OpenAPI spec generated assumed all fields with "omitempty" in their json tags are optional. This should be still the case (as well as +optional tag) until these two things happen:
- We update all documentation asking developers to use +optional (My bad, I should have added this after the +optional PR)
- We fix swagger 1.2 spec generator to use +optional instead of omitempty.

OpenAPI Bugfix: []byte should be treated as integer array
data field of v1.Secret is a map of string to byte array. Generated spec should generate a map of string to (type="string", format="byte" that means map of base64 string) however current code converts it to an array of integer that is wrong.
