Modifying the notifier based on a stage status.

[dsenecalb]

Hi @srinivasupadhya:

I was trying to make an if condition based on the stage state and result. However, every time I run a pipeline, the following error:

Interaction with plugin with id 'email.notifier' implementing 'notification' extension failed while requesting for 'stage-status'. Reason: [Unable to de-serialize json response. Empty response body]

The goal is to filter out the statuses of a stage.

And this error appears when the current stage status is not the one that is required.
