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. All component services are replaced by them from the loki-mixin
2. The memberlist service is replaced by the one from the loki-mixin
