Graduate metrics/v1alpha1 to v1beta1
This introduces v1beta1 of the resource metrics API, previously in alpha.
The v1alpha1 version remains for compatibility with the Heapster legacy version
of the resource metrics API, which is compatible with the v1alpha1 version. It also
renames the v1beta1 version to `resource-metrics.metrics.k8s.io`.
The HPA controller's REST clients (but not the legacy client) have been migrated as well.
Part of kubernetes/features#118.
```release-note
Migrate the metrics/v1alpha1 API to metrics/v1beta1. The HorizontalPodAutoscaler
controller REST client now uses that version. For v1beta1, the API is now known as
resource-metrics.metrics.k8s.io.

Build test targets for all server platforms
**What this PR does / why we need it**:
🤦
I really should have checked this before code freeze, but tbh forgot it in the rush. Also I thought this was the case already...
As part of https://github.com/kubernetes/features/issues/288; these binaries should be built for all server platforms indeed.
This is just a straightforward add to that list.
Can we please get this into v1.8?
There is virtually no risk involved here really...

Add EgressRule to NetworkPolicy
**Which issue this PR fixes**: fixes#50453
**Special notes for your reviewer**:
- Please take a look at the comments for the various types. I tried to mimic some of the language used in the Ingress comments, but I may have mangled some sentences.
- Let me know if I should add some test cases for validation. I have 2-3, and did not think it was necessary to replicate each case already covered in ingress.
**Release note**:
```
Add egress policies to NetworkPolicy

Update godep-licenses script to work on darwin
**What this PR does / why we need it**:
When reviewing #51766, noticed that the godep licenses script has slightly different output on darwin (using the BSD md5sum) and linux (using the GNU md5sum).
This adds an awk trim to ensure that the output is the same on both platforms.

Limit events accepted by API Server
**What this PR does / why we need it**:
This PR adds the ability to limit events processed by an API server. Limits can be set globally on a server, per-namespace, per-user, and per-source+object. This is needed to prevent badly-configured or misbehaving players from making a cluster unstable.
Please see https://github.com/kubernetes/community/pull/945.
**Release Note:**
```release-note
Adds a new alpha EventRateLimit admission control that is used to limit the number of event queries that are accepted by the API Server.

Add IPAM controller for synchronizing node pod CIDR range allocations between the cluster and the cloud (alpha feature)
```release-note
IPAM controller unifies handling of node pod CIDR range allocation.
It is intended to supersede the logic that is currently in range_allocator
and cloud_cidr_allocator. (ALPHA FEATURE)
Note: for this change, the other allocators still exist and are the default.
It supports two modes:
* CIDR range allocations done within the cluster that are then propagated out to the cloud provider.
* Cloud provider managed IPAM that is then reflected into the cluster.
```

add reconcile command to kubectl auth
This pull exposes the RBAC reconcile commands through `kubectl auth reconcile -f FILE`. When passed a file which contains RBAC roles, rolebindings, clusterroles, or clusterrolebindings, it will compute covers and add the missing rules.
The logic required to properly "apply" rbac permissions is more complicated that a json merge since you have to compute logical covers operations between rule sets. This means that we cannot use `kubectl apply` to update rbac roles without risking breaking old clients (like controllers).
To solve this problem, RBAC created reconcile functions to use during startup for "stock" roles. We want to offer this power to users who are running their own controllers and extension servers.
This is an intersection between @kubernetes/sig-auth-misc and @kubernetes/sig-cli-misc

Switch away from gcloud deprecated flags in compute resource listings
**What is fixed**
Remove deprecated `gcloud compute` flags, see linked issue.
**Which issue this PR fixes**:
fixes#49673
**Special notes for your reviewer**:
The change in `gcloudComputeResourceList` in `test/e2e/framework/ingress_utils.go` isn't strictly needed as currently no affected resources are called on within that file, however the function has the _potential_ to access affected resources so I covered it as well. Happy to change if deemed unnecessary.

Implement StatsProvider interface using cadvisor
Ref: https://github.com/kubernetes/kubernetes/issues/46984
- This PR changes the `StatsProvider` interface in `pkg/kubelet/server/stats` so that it can provide container stats from either cadvisor or CRI, and the summary API can consume the stats without knowing how they are provided.
- The `StatsProvider` struct in the newly added package `pkg/kubelet/stats` implements part of the `StatsProvider` interface in `pkg/kubelet/server/stats`.
- In `pkg/kubelet/stats`,
- `stats_provider.go`: implements the node level stats and provides the entry point for this package.
- `cadvisor_stats_provider.go`: implements the container level stats using cadvisor.
- `cri_stats_provider.go`: implements the container level stats using CRI.
- `helper.go`: utility functions shared by the above three components.
- There should be no user visible behaviors change in this PR.
- A follow up PR will implement the StatsProvider interface using CRI.

Fix rsync issue when maintaining data containers
**What this PR does / why we need it**:
When we stopped syncing the full .git dir into the container and created a dummy git tree, an issue arose if you're maintaining a data dir volume. The git tree created in the container wouldn't be updated if we make more commits and sync them in, and would cause a dirty tree.
This PR changes the rsync flags so that "H" filtered files are hidden from rsync on the source side, and if they exist on the destination side, they will be deleted.
