Extend autodection of reframe for custom attributes #3597
Description
Right now, the autodetect job of reframe only gets information for the processor. It would be interesting to give users more flexibility on this job. Maybe the can provide their own commands/functions in the configuration of reframe (similar to the json_formatter) and then the respective parser.
This data should somehow be stored and become available in the current_partitions in similar way that the processor info are available. We could simply have more attributes in the extras of the partition.
