Subject: Use legacy label name validation
Forwarded: not-needed
Last-Update: 2025-02-20
Due to a backwards-incompatible change in prometheus/common v0.62.0,
override the global models.NameValidationScheme variable to enforce
legacy (non-UTF-8) label names. This patch can be dropped once the
prometheus package is updated to one that supports UTF-8 label names,
i.e., v2.55.0 or later.
