test/perf: Start iperf3 server less often

Browse source 
Currently we start both the iperf3 server(s) and client(s) afresh each time
we want to make a bandwidth measurement.  That's not really necessary as
usually a whole batch of bandwidth measurements can use the same server.

Split up the iperf3 directive into 3 directives: iperf3s to start the
server, iperf3 to make a measurement and iperf3k to kill the server, so
that we can start the server less often.  This - and more importantly, the
reduced number of waits for the server to be ready - reduces runtime of the
performance tests on my laptop by about 4m (out of ~28minutes).

For now we still restart the server between IPv4 and IPv6 tests.  That's
because in some cases the latency measurements we make in between use the
same ports.
