refs #5702 get perf_iibench to work under with --only_create/--only_stress/--num_elements by:

1. disabling unique checks when num_elements > 0 (ie: the table was pre-created)
2. filling the tables with valid iibench-like data during the create phase (intercept with a function pointer, as best as I can think of for now)
3. wrapping the pk back to the beginning of the table when bounded_element_range && num_elements > 0
