Add stress test for opening many database instances

[cb1kenobi]

Harper opens a lot of database instances and column families, so this stress test will test this scenario.

stress-test and benchmark were not correctly added to the tsconfig and thus types weren't being enforced. After adding these, I needed to add types to the benchmark setup.ts.

Fixes #473
