Matt T. Proud c10780c966 Introduce telemetry for rule evaluator durations.
This commit adds telemetry for the Prometheus expression rule
evaluator, which will enable meta-Prometheus monitoring of customers
to ensure that no instance is falling behind in answering routine
queries.

A few other sundry simplifications are introduced, too.
