Fix #4362 .

QuickPulse has its own internal buffer. If the first "Fake Exception" (from the health check) was buffered but not yet sent when mockedIngestion.resetData() was called, it will be delivered to the new LiveMetricsVerifier along with the
second exception.

The PR adds a specific servlet for the health check to avoid the race condition
