Make fake client actions use fully qualified resource
The output of a versioned clientset is version object. The fake client used to assume only internal objects will be returned. This PR removes this assumption by making fake actions initialized with a fully qualified resource instead of a resource string.
We have to regenerate fake clients in release_1_2 clientset to let it compile. For the test fakes, we are breaking the backwards compatibility promise.
Part of #24155.

make storage enablement, serialization, and location orthogonal
This allows a caller (command-line, config, code) to specify multiple separate pieces of config information regarding storage and have them properly composed at runtime. The information provided is exposed through interfaces to allow alternate implementations, which allows us to change the expression of the config moving forward. I also fixed up the types to be correct as I moved through.
The same options still exist, but they're composed slightly differently
1. specify target etcd servers per Group or per GroupResource
1. specify storage GroupVersions per Groups or per GroupResource
1. specify etcd prefixes per GroupVersion or per GroupResource
1. specify that multiple GroupResources share the same location in etcd
1. enable GroupResources by GroupVersion or by GroupResource whitelist or GroupResource blacklist
The `storage.Interface` is built per GroupResource by:
1. find the set of possible storage GroupResource based on the priority list of cohabitators
1. choose a GroupResource from the set by looking at which Groups have the resource enabled
1. find the target etcd server, etcd prefix, and storage encoding based on the GroupResource
The API server can have its resources separately enabled, but for now I've kept them linked.
@liggitt I think we need this (or something like it) to be able to go from config to these interfaces. Given another round of refactoring, we may be able to reshape these to be more forward driving.
@smarterclayton this is important for rebasing and for a seamless 1.2 to 1.3 migration for us.

etcd3 store: provide compactor util
What's this PR?
- Provides a util to compact keys in etcd.
Reason:
We want to save the most recent 10 minutes event history. It should be more than enough for slow watchers. It is not number based, so it can tolerate event bursts too. We do not want to save longer since the current storage API cannot take advantage of the multi-version key yet. We might keep a longer history in the future.

Remove requirement that Endpoints IPs be IPv4
Signed-off-by: André Martins <aanm90@gmail.com>
Release Note: The `Endpoints` API object now allows IPv6 addresses to be stored. Other components of the system are not ready for IPv6 yet, and many cloud providers are not IPv6 compatible, but installations that use their own controller logic can now store v6 endpoints.

Enable protobuf compilation by default
Enables protobuf compilation, build verification checks, and generates all initial code.
kubectl is now 47M on OSX, build time from clean on a 2014 MBP (4 core) on Go 1.6 is ~150s.

etcd3/store: support TTL in Create, Update
ref: https://github.com/kubernetes/kubernetes/issues/22448
What's included in the PR?
- Support TTL keys in Create() and Update()
- Simple testing for create
Note
- Have TTL keys in a long window (5min) in one lease. I'm not sure if we should do it right now. We could just implement it as simple as is. Once we have etcd3 work done we could start testing and measuring with some realistic load.

client-gen: use serializer instead of codec for versioned client
For a versioned client, because the output of every client method is a versioned object, so it should use a serializer instead of a codec that does conversion.

Fix unintended change of Service.spec.ports[].nodePort during kubectl apply
Please refer #23551 for more detail. @bgrant0607 I think this simple fix should be ok to reuse nodePort. @thockin ptal.

genericapiserver: Moving more flags to ServerRunOptions
Moving more apiserver flags to generic api server.
With this change, most of the Config is created in genericapiserver.NewConfig(). The plan is to move everything there.
I didnt touch Storage related params as they are being changed in https://github.com/kubernetes/kubernetes/pull/23208.
And I will handle authz and authn in another PR (need to figure out a few things).

Don't log private SSH key
Log files may have more inclusive permissions than private SSH keys, and as such we should not log the key, even if it looks invalid. I accidentally leaked my key this way when posting e2e test logs.
