Nathan LeClaire 76c7accda0 Add heartbeat / automatic server cleanup code ...

This replaces the previous method of attempting to clean up servers when
an unexpected exit occurs in the client (e.g. SIGINT or panic) by a
heartbeat protocol.  If the server does not hear from the connecting
client within a certain interval of time (500ms in this commit), it will
de-activate itself.  This prevents dangling Docker Machine server
processes from accumulating.
