A service record exists in the cache, and a query transmission
with a long duration has been scheduled because the service
information was recently updated. However, the query will be sent
immediately if a new discovery/resolution/service info callback
listener is registered. Therefore, to reduce unnecessary queries
in aggressive query mode, if a service exists in the cache, the
query timing should either reuse the scheduled run or use a
backoff time if there is no scheduled run.
