Since not all pipelines need to notify ALL (the default [1]) - allow the
pipeline config to specify the notification level via success/failure
action config.
* Rationale
The reason to do this is to avoid spamming everyone that gets
notifications for a change. For instance in the case where a vote is
not negative and the pipeline has mostly trivial jobs it would be nice
to avoid sending emails.
* Problems/also considered
This is potentially a breaking change if the votes that users have
configured are named "notify".
I would think the ultimate fix would be to, instead of having ad-hoc
parsers for votes, make the gerrit key have a ReviewInfo object (as
Yaml) as its value.
I don't want to do that as part of this review since that would be a
breaking change.
