Rerun flaky PinotDB integration test

[Taragolis]

Time to time we have this error on public runner.

self = <tests.integration.providers.apache.pinot.hooks.test_pinot.TestPinotDbApiHookIntegration object at 0x7f36f132d450>

    def test_should_return_records(self):

        sql = "select playerName from baseballStats  ORDER BY playerName limit 5"
        records = hook.get_records(sql)
>       assert [["A. Harry"], ["A. Harry"], ["Aaron"], ["Aaron Albert"], ["Aaron Albert"]] == records

Most probably the nature of this error some kind of race condition:

1. PinotDB test service marked healthy before data actually persist into test database
2. Test get 0 record as result test failed.

In case of failure test will rerun after 30 seconds but only once.

In additional I remove flaky as dev-dependency because it use the same marker @pytest.mark.flaky as pytest-rerunfailures plugin.

Yes. The problem here is that starting quickstart merely starts the injestion job for baseball stats and does not wait for completion. I considered changing health-check but that would be quite complex and re-running failed test in this case is much simpler solution
