This commit introduces a new feature to optimize the removal of
expired services. After the query is sent, a task is scheduled
with a 2-second delay to wait for responses. During this delay,
if a service response is received, the service information is
updated, and the service is removed from the removal list. After
the delay, services that are expired, have sent a query, and for
which the query time was 2 seconds ago are removed, and listeners
are notified.
