docs: Link a pseudo destination ID to a real destination handler. This is used to link destination
  IDs created for remote durable pub/sub to the appropriate Pub/Sub destination handler which
  hosts a localization of some durable subscription.
  
  @param destinationUuid The pseudo destination ID to link.
  @param handler The pub/sub (well BaseDestinationHandler anyway) which the destination is linked to.
