Support a generic `run_sql` goja command for seeding database.

[jacobblock]

What would you like to be added: It looks like cmd_seed has a couple of functions manually added, graphql and import_csv. It would also be nice to have something generic like run_sql so we can populate the database directly and not write out 10+ csv files for initializing tables.

Why is this needed: Convenience and allow for more flexibility in the seed runner.
