If an exception is reported by the storage layer, the dispatcher logs the error but does not propagate it. Stevedore plugin framework also does not propagate the exception back to the caller. The sample is not requeued since collector does not get the exception and returns a Handled NotificationResult. This fix raises the exception in the database dispatcher and enables Stevedore to propagate exceptions to the collector. Change-Id: I341ad92df050bf0f474b07c3f27c68cdb4f4e59b Closes-Bug: 1433881
