BackendListener : Allow implementations to drop samples

[asfimport]

@pmouawad (Bug 57537):
In some cases it might be useful for BackendListenerClient implementations to drop some SampleResults if they are not interested:

• Listener that only implements "teardownTest" for example
• Listener that wants to filter some SampleResults
  ....

OS: All
