testbed: sometimes process is left running holding Jaeger UDP port 6831

[pjanotti]

$ lsof -i :6831
COMMAND     PID USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
otelsvc_d 45898   pj   10u  IPv6 0x6abd86876f460e5b      0t0  UDP *:ambit-lm

I will see if I can get better repro steps but it seems just by running testbed with performance tests.

Can you check if otelsvc process stays in running in memory?

$ lsof -i :6831

otelsvc_d 50764   pj   10u  IPv6 0x6abd86877042bdbb      0t0  UDP *:ambit-lm
$ ps -p 50764

This can happen if TestCase.Stop() hangs before killing service process and go test eventually kills the test.
