system-traffic: Introduce OVS_START_L7 macro.

Browse Source 
All of the commands starting L7 servers duplicate detailed specifics
which inhibits readability, and makes it difficult to ensure that the
servers are ready before the test proceeds. Add a new macro that
provides simpler semantics from the test perspective and hide the
details in the macro. A followup patch will extend this macro to ensure
that servers are ready to serve requests before the test proceeds.
