Add ability to disable alerts from (pipeline, searches) combinations
Followup from the semi-regular RRT call of Tuesday May 23.
It seems we currently have the ability to disable alerts from individual pipelines, but not from (pipeline, search) combinations. I would like to request the latter ability as well. The use case is that we could in principle have problems from e.g. PyCBC Live early-warning, but not from PyCBC Live full-bandwidth.
