Description

Is your feature request related to a problem? Please describe. When making prometheus alert or recording rules, there's a system to test them. Making Loki alert or recording rules is frustrating since there's no clear testing system.

Describe the solution you'd like I'd like a system for Loki that mirrors the prometheus system described at https://prometheus.io/docs/prometheus/latest/configuration/unit_testing_rules/.

Describe alternatives you've considered Keeping things in prometheus as much as possible, so promtool test can be used. Making Loki recording rules only if possible.

Additional context This could potentially be a loki tool, or some kind of cortextool extension?
