Use BasicParser in trivial construction
Remove unnecessary include of PlanOperation
Small cleanup in HashJoinProbe
Move to abstract resources as operational data

We remove two distinct data structures for specific types and
replace this structure with a more generic one. The old interface
stays intact for AbstractTables and AbstractHashtables.

Further we clean up some details in PlanOperation and add a
set of tests for OperationData's behavior.
