Returns all metrics that evaluate to “true” based on the rules.
If no filter has a label specified, it uses RegexSet for all regexes.
TODO: optimize using more RegexSet without labels…
TODO: Support delta-based divides.
Returns all metrics that evaluate to “true” for the regex on the metrics name, not the label.
If called in a loop, use “lazy_static” to ensure that regular expressions
are compiled exactly once.
