[integration tests] add a smoketest for pulsar standalone (#2732)

*Motivation*

Ideally we should run all integration tests on both cluster mode and standalone
mode. However the apache ci can't really afford to do so. so we run all the integration
tests on cluster mode. We only run basic validation and test new features (e.g. state)
on standalone.

*Changes*

Add PulsarStandalone related test base and suite and a simmple smoke test.
This would set the framework for integration tests for state
