1f6baa6549 Move userspace code to sub-package in proxy. 
Moves the userspace code in proxy to a sub-package and adds the
ProxyProvider interface.

This is in preparation for landing an implementation of
https://github.com/GoogleCloudPlatform/kubernetes/issues/3760, which
will mostly be in another sub package for iptables.

4b9b7ec2f9 Continue to support (deprecated) publicIPs 
Not doing so breaks e2e tests and people that may be using them,
even though we will eventually want to stop supporting this now
that we have better alternatives for typical use cases (NodePort)

1ad4549f5f Proxy infrastructure for NodePorts 
A service with a NodePort set will listen on that port, on every node.

This is both handy for some load balancers (AWS ELB) and for people
that want to expose a service without using a load balancer.

4b29947652 pkg/proxy: panic if run out of fd 
When proxy runs out of fd, it fills the logs with error message.
From #6716, it is better to just panic().

51db3bd654 Create a new testclient package that can be backed by disk files 
Standardize how our fakes are used so that a test case can use a
simpler mechanism for providing large, complex data sets, as well
as represent queries over time.

8ae203825b Implement multi-port endpoints 
Instead of endpoints being a flat list, it is now a list of "subsets"
where each is a struct of {Addresses, Ports}.  To generate the list of
endpoints you need to take union of the Cartesian products of the
subsets.  This is compact in the vast majority of cases, yet still
represents named ports and corner cases (e.g. each pod has a different
port number).

This also stores subsets in a deterministic order (sorted by hash) to
avoid spurious updates and comparison problems.

This is a fully compatible change - old objects and clients will
keepworking as long as they don't need the new functionality.

This is the prep for multi-port Services, which will add API to produce
endpoints in this new structure.

2ca265ae3b Remove --etcd_servers flag from kubelet and proxy. 
All the distros that use this have been updated,
or have PRs out to update them, or owners
have been asked to fix RPMs.

Removing this prevents further use of this model.

Remove now dead code: EtcdClientOrDie

Remove now dead pkg/proxy/config/etcd.go.

Remove unused imports.
