Runtime test batch executor

Earlier we were docker exec-ing each test at a time. However invoking the test
framework has a fixed overhead which made it infeasible to make the runtime
tests run as presubmits. This change now executes tests in batches of 50 (can
be altered). This really speeds up testing process.

With this change, the following tests can be run in reasonable times:
- Go
- Nodejs
- Php
- Python
