Serialized protobuf should have stable map order
Leverage `stable_marshaller_all` tag in gogo-protobuf to ensure all of our maps have stable ordering when serialized to protobuf. This preserves the behavior from JSON that we rely on to avoid writing to etcd except when the content has changed.
Will slightly increase allocations (1 slice per non-empty map in an object) during Encode, which has a minor impact on CPU. However, avoiding writes when a client issues a blind put results in significantly less CPU across the whole cluster (avoiding a new etcd version for an Endpoints object might save ~1 core/sec on large clusters).
Fixes#47678
```release-note
The protobuf serialization of API objects has been updated to store maps in a predictable order to ensure that the representation of that object does not change when saved into etcd. This prevents the same object from being seen as being modified, even when no values have changed.

Mark Static pods on the Master as critical
fixes#47277.
A known issue with static pods is that they do not interact well with evictions. If a static pod is evicted or oom killed, then it will never be recreated. To mitigate this, we do not evict static pods that are critical. In addition, non-critical pods are candidates for preemption if a critical pod is scheduled to the node. If there are not enough allocatable resources on the node, this causes the static pod to be preempted.
This PR marks all static pods in the kube-system namspace as critical.

mark --network-plugin-dir deprecated for kubelet

**Which issue this PR fixes** : fixes#43967
**Special notes for your reviewer**:
**Release note**:

The default marshalers from gogo-protobuf do not order keys, which means
successive serializations of the same data would result in same bytes.
Kubernetes leverages stable serialization to avoid excessive writes to
etcd when body content has not changed, which reduces the amount of
watch traffic generated by successive callers.
This will have a small memory impact on objects which have maps -
allocating a new string array for each map key. All maps must be keys
because we serialize those to JSON, so non-string types are not
relevant.

Add files specified in the kube config as a potential source of cert/…
Fixes#47208
Add files specified in the kube config as a potential source of cert/key data.
Without this change, the kubelet won't use certificates that are specified using file paths in the kubeconfig file. This specifically affects GCE clusters started with kube-up.sh with the RotateKubelet*Certificate feature gate flags enabled, but may affect other configurations.
This change only affects feature gated alpha code.

bazel: stamp multiple packages by using x_defs instead of linkstamp in go_binary rules
**What this PR does / why we need it**: Fixes regression introduced sometime in the last few months that prevented bazel-built clusters from identifying version properly.
It does so by updating the bazelbuild/rules_go and kubernetes/repo-infra dependencies to support using stamp values in `go_binary` `x_defs`, and then changing our `go_binary` rules to use `x_defs` instead of `linkstamp`.
This whole charade is necessary because we need to stamp version information in multiple packages.
This pretty much only affects the bazel build, so it should be low risk.

StorageOS Volume Plugin
**What this PR does / why we need it**:
This PR adds a new volume plugin for StorageOS volumes. StorageOS runs as a container on Kubelet nodes, aggregating local or attached storage and making its capacity available to all nodes within the cluster. More information at http://storageos.com.
The StorageOS plugin supports:
1. Dynamic Provisioning using Storage Classes
2. Persistent Volumes and Persistent Volume Claims.
**Which issue this PR fixes**
A feature request has been created:
https://github.com/kubernetes/features/issues/190
This isn't on the schedule for 1.6 as I wasn't sure when it would be ready. We intend to make the StorageOS container openly available within the 1.6 lifetime.
**Special notes for your reviewer**:
Separate commits for feature and godep changes.
**Release note**:
```release-note
StorageOS Volume Driver
[StorageOS](http://www.storageos.com) can be used as a storage provider for Kubernetes. With StorageOS, capacity from local or attached storage is pooled across the cluster, providing converged infrastructure for cloud-native applications.
