Replace values within CSV_DATA and JSON_DATA dictionaries with lists of tuples, add data supplier config attribute
Replace values within CSV_DATA and JSON_DATA dictionaries with lists of tuples, add data supplier config attribute

Under previous implementation, tables were being populated in random order, which caused loading to fail because some tables
must be populated before others.  Instead, the main keys within the CSV_DATA and JSON_DATA dictionaries remain, but the
values are now lists of tuples in the order of table population.

Also, add attribute that will contain name of third-party data supplier.
