s4:operational module - move and enhancements

This moves the "operational" LDB module to the right place under "dsdb/samdb/ldb_modules"
(suggested by abartlet) and enhances it for supporting dynamic generated
"primaryGroupToken" for AD groups. This should fix bug #6466.

-  createTimestamp: HIDDEN, searchable, ldaptime, alias for whenCreated
-  modifyTimestamp: HIDDEN, searchable, ldaptime, alias for whenChanged
-
-     for the above two, we do the search as normal, and if
-     createTimestamp or modifyTimestamp is asked for, then do
-     additional searches for whenCreated and whenChanged and fill in
-     the resulting values
-
-     we also need to replace these with the whenCreated/whenChanged
-     equivalent in the search expression trees
-
-  whenCreated: not-HIDDEN, CONSTRUCTED, SEARCHABLE
-  whenChanged: not-HIDDEN, CONSTRUCTED, SEARCHABLE
-
-     on init we need to setup attribute handlers for these so
-     comparisons are done correctly. The resolution is 1 second.
-
-     on add we need to add both the above, for current time
-
-     on modify we need to change whenChanged

-
-     for this one we do the search as normal, then add the static

-
-  structuralObjectClass: HIDDEN, CONSTRUCTED, not-searchable. always same as objectclass?
-
-     for this one we do the search as normal, then if requested ask
