Cache refresh should remove persons sub entries on removal

[yurem]

If ORM not supports cascade removal CR should remove ou=pairwiseIdentifiers,inum=person_inum,ou=people,o=gluu and ou=fido,inum=person_inum,ou=people,o=gluu related entries

In order to check if ORM supports this server can use persistenceEntryManager.hasBranchesSupport(inum=person_inum,ou=people,o=gluu)

To remove entries server can use persistenceEntryManager.remove(String primaryKey, Class<T> entryClass, Filter filter, int count);
