Describe the enhancement:

We introduced different type behavior (use_types, rate_counters) when using Prometheus collector in 7.7. It would be nice to offer something similar for metrics coming through remote_write, for consistency and users profit.

Remote write API schema is typeless so we would need some heuristics to detect the original type where needed. For instance:

• Metrics ending up in _bucket with a le label are part of a histogram.
• Metrics matching *_total are counters. We could make this a configurable regexp list, so users can tweak it to its needs.
