/**
 * The TCP out-bound tunnel is almost identical to the in-bound tunnel.
 * We use MetisStreamConneciton for the out-bound tunnels too.  We call a different
 * constructor than the in-bound so the MetisStreamConneciton knows that it is starting
 * unconnected and needs to wait for the Connected event before putting it in the UP state.
