Backout previous commit a0be501f4c64023e54bbe609d8021d3bd2d24b5a
Added package aggregation to SQL query generated if applicable
Package aggregation works similar to what DataIterator does but is executed inside MySQL
Fixed CounterInterpreter consumption and average calculation when tuples is specified.
Otherwise, edge counter values would be mangled by the data packaging algorithm in DataIterator leading to up to 100% deviation of values generated for tuples=2.
Added database section:
- number of records in data table
- size of data table (bytes)
