> This commit extends the timeout for service_may_be_active()
> from 100ms to 1000ms. Local testing on a idle and loaded system
> (compiling DPDK with all cores) always completes after 1 ms.
> 
> The wait time for a service-lcore to finish is also extended
> from 100ms to 1000ms.
> 
> The same timeout waiting code was duplicated in two tests, and
> is now refactored to a standalone function avoiding duplication.
