Anton Tolchanov	5336362e64	prober: export probe class and metrics from bandwidth prober ... - Wrap each prober function into a probe class that allows associating metric labels and custom metrics with a given probe; - Make sure all existing probe classes set a `class` metric label; - Move bandwidth probe size from being a metric label to a separate gauge metric; this will make it possible to use it to calculate average used bandwidth using a PromQL query; - Also export transfer time for the bandwidth prober (more accurate than the total probe time, since it excludes connection establishment time).
