Test randomly failling

[ph]

The current build is failling on travis, Probably some test are flaky or the travis box is a bit saturated.

Failures:
  1) inputs/kafka #kafka-decorate should show the right topic and group name in decorated kafka section
     Failure/Error: wait(timeout_seconds).for { queue.length }.to eq(num_events)
       expected: 103
            got: 0
