Proposal
In order to stop targets from overloading label values and also the metric __name__ index, add a scrape config limiter that limits the number of unique label values per scrape.
This will protect, for example:
- When other metric systems are translated to Prometheus incorrectly and tag values become part of the metric name.
- When a piece of data is not filtered and exposed as thousands of label values.
