* A ServerIdentitiesProvider is responsible for providing the identities

* for PEP (XEP-0163): {@code
*
* When the server starts up, IQDiscoInfoHandler will request to all the services that implement
* the ServerIdentitiesProvider interface for their identities. Whenever a disco request is received
* IQDiscoInfoHandler will add to the provided information all the collected identities. Therefore, a
* service must implement this interface in order to offer/publish its identities as part of the
* server identities.
