Add SSH Agent Primitives and usage
Debugging some issues revealed a problem in the __eq__ method that is
patched here. This produced some red herring backtraces unnecessarily.
It's worth noting that close_fds on this subprocess.Popen call is
critical to the health of any other processes being spawned from Zuul.
Without it, git processes run by the git module went defunct and locked
things up in weird ways.
