The RHOBS Loki manifests for stage and production rollout is currently based on custom JSONNet component hosted on the observatorium/observatorium repository. This component was created back in 2020 when the official Grafana loki-mixin for production deployments did not support by default memberlist/boltdb-shipper setups. Since 2021 this is the case and keeping our own loki component is cumbersome. In fact we need to implement all migrations for each Loki release.

Acceptance Criteria

1. Loki ConfigMap is generated entirely from the loki-mixin
2. Loki ConfigMap generation replaces the replication factor CLI arg with an similar environment variable
3. Generated ConfigMap includes defaults in limit config as previously introduced
