Redirect worker output via kubectl attach

[omus]

Alternative fix for #56 which currently is non-functional. The main issue seems to be that I can't seem to get stdin/stdout to work correctly with kubectl attach. There is one commit on this branch that works due but it only uses stdout and requires us to slow the worker down such that the output of the worker IP/port can be captured by the manager.
