A rework of https://github.com/montag451/spnego-proxy/
plainproxy: just a WebHDFS proxy for the namenode, doing nothing but proxying. Good to mediate latency and troubleshoot protocol.
no-consul: does SPNEGO, but doesn't use consul
consulspnegoproxy: does SPNEGO and negotiates with Consul.
(nah, i did not bother to write a consul-plain proxy, but it's a trivial matter)
Find the last versions i bothered to build on Docker Hub.
