Related issue: #1133 Motivation: There is no support for client socket connections via a proxy server in Netty. Modifications: - Add a new module 'handler-proxy' - Add ProxyHandler and its subclasses to support SOCKS 4a/5 and HTTP(S) proxy connections - Add a full parameterized test for most scenarios - Clean up pom.xml Result: A user can make an outgoing connection via proxy servers with only trivial effort.
