Implement Grafana Loki, Mimir, and Grafana for better log parsing and monitoring of the search-engine-bc

As per @WadeBarnes comment: https://github.com/bcgov/orgbook-configurations/pull/137#issuecomment-1719716946

We have limited options for parsing logs within Kibana.

- Deploy [Grafana](https://grafana.com/oss/grafana/) and [Loki](https://grafana.com/oss/loki/) in 8ad0ea-tools namespace.
- Deploy [Agent](https://grafana.com/oss/agent/) in 8ad0ea-prod, and other namespaces as necessary, to collect logs and push to Loki.

Since Grafana Agent can collect both, logs and metrics, we can use Grafana Mimir to store/aggregate/query collected metrics. This can also allow correlating logs and metrics within Grafana if necessary.
- Deploy [Mimir](https://grafana.com/oss/mimir/) in -tools namespace.
