feat: add missing SOCKS5 features

Browse Source 
Goal of this commit is to add some missing features when the
Kubernetes API is accessed through a SOCKS5 proxy. That's for
example the case when port-forwarding is used (`kubectl port-forward`)
or when exec'ing inside a container (`kubectl exec`), with this
commit it'll now be possible to use both.

go-socks5 [![Build Status](https://travis-ci.org/armon/go-socks5.png)](https://travis-ci.org/armon/go-socks5)
=========
Provides the `socks5` package that implements a [SOCKS5 server](http://en.wikipedia.org/wiki/SOCKS).
SOCKS (Secure Sockets) is used to route traffic between a client and server through
an intermediate proxy layer. This can be used to bypass firewalls or NATs.
Feature
=======
The package has the following features:
* "No Auth" mode
* User/Password authentication
* Support for the CONNECT command
* Rules to do granular filtering of commands
* Custom DNS resolution
* Unit tests
TODO
====
The package still needs the following:
* Support for the BIND command
* Support for the ASSOCIATE command
Example
=======
Below is a simple example of usage
```go
// Create a SOCKS5 server
conf := &socks5.Config{}
server, err := socks5.New(conf)
if err != nil {
panic(err)
}
// Create SOCKS5 proxy on localhost port 8000
if err := server.ListenAndServe("tcp", "127.0.0.1:8000"); err != nil {
panic(err)
}
```
