SQL Health Check - Handle HTTP exception

Related issues

• FHIR Health Checks can fail due AAD misconfiguration. And those failures can happen when one of our internal components try to acquire the connection string to SQL.

Testing

Added new unit test to ensure errors in SQL Health Checks are handled properly.

Is there also some way to check if the access is controlled by the customer? Maybe we can pass in a config or something that will have a flag if the SQL connection is customer controlled?

I'm worried about this filtering out health check failures that are caused by actual bugs. For example, in Dicom SQL is completely internal so there's no way a customer could mess anything up. If we get a Forbidden or Unauthorized exception, we would want to throw an exception here because that means something to do with our token is messed up.
