Adds the keda user as a multi tenant user to mimir
What
- Adds the keda user as a multi tenant user to Mimir.
- Fixes regex pattern matching.
Why
Keda is used for autoscaling decisions with promql lookups to prometheus/mimir across multiple clusters using different tenants. This enables keda to supply its own X-Scope-OrgID
header to more easily switch tenants.
