Contribute parts from my "clone"

[ondrej-smola]

@jdef I have been working on my own go http mesos driver as this repository was not very active last months and I needed operator api quickly. I have implemented Operator API and own low and high level API for proto 1.1. I would like to contribute at least some parts back repository.

[jdef]

I've just added (to the master branch) the agent protos for 1.2.x. No helper APIs yet. Are you still interested in contributing to the agent operator API for mesos-go? Would be interested to learn what approaches have/haven't worked for you.

@jdef Definitely interested in contributing still. The mesos-cli tool I released a few months ago is based off an older fork of mesos-go where I added code for the operator API. I will try to bring my tool in line with current master and contribute some of my helper code here. Looks like @ondrej-smola's branch is also still being maintained.
