Existing service functions allow us to stop a service, but doing so doesn't guarantee that the service has finished running on a service core. This commit introduces rte_service_may_be_active(), which returns whether the service may be executing on one or more lcores currently, or definitely is not. The service core layer supports this function by setting a flag when a service core is going to execute a service, and unsetting the flag when the core is no longer able to run the service (its runstate becomes stopped or the lcore is no longer mapped). With this new function, applications can set a service's runstate to stopped, then poll rte_service_may_be_active() until it returns false. At that point, the service is quiesced.
