Subscribes to feedback indicator information
This function allows a process to receive the same information as the jobs_server any time the information changes.
The notifications are delivered on the format{jobs_indicators, Info},
where
Info :: [{IndicatorName, LocalValue, Remote}]
Remote :: [{NodeName, Value}]
This information could be used e.g. to aggregate the information and generate
new sampler information (which could be passed to a sampler plugin using
tell_sampler/2, or to a specific queue using jobs:ask_queue/2.
tell_sampler(P, Msg) -> any()
