This client prototype should have a similar CLI to what we eventually want to build into the Mesos or DC/OS CLI.
Streaming HTTP Client
client task exec [--tty] [--interactive] <task-id> <cmd> [<args>...]
client task attach [--tty] [--interactive] <task-id>
--tty Allocate a tty on the server before
attaching to the container.
--interactive Connect the stdin of the client to
the stdin of the container.
