!per #18463 Make Persistence Query API explorable

Browse source 
* make the standard queries "single method interfaces" that may be implemented
  by a query journal plugin
* remove hints (major problems with varargs anyway), the hints for standard
  queries  should be given in configuration instead, e.g. refresh-interval
