Description
**Is your feature request related to a problem? Please describe.**
Previous versions of prometheus accepted a limited set of characters as metric or label names, but prometheus 3.0 supports a broader range of strings, including dots and dashes.
**Describe the solution you'd like**
Rather than always escaping prometheus metric names, crdb should control escaping behavior using content negotiation per prometheus 3.0.
