when "radosgw-admin lc process" is called, and there are buckets that have bucket notification events set with "ObjectLifecycle:*" or "LifecycleExpiration:*" event types, the events are sent from the radosgw-admin process itsef.
as part of this fix: https://tracker.ceph.com/issues/65337
endpoints (kafka/amqp/http) are not going to run in the radosgw-admin, which means sending these notifications will fail. which is probabnly ok as it is not expected that we send them from the radosgw-admin anyway.

• not try to send them from radosgw-admin
• add a note to documentation that LC events should be using only persistent topics, otherwise they will not be sent when "radosgw-admin lc process" is used
