WIP: Remove patches, enable Prometheus exporters and configure them for external PG, Redis.
Remove Git Hooks patch, it's ConfigMap, and references.
Enable and configure additional Prometheus exporters in 8.17:
- gitlab-monitor
- redis_exporter
- postgres_exporter
Two bugs still in RC3:
- We are unable to modify the listen address of Prometheus, so it is currently inaccessible remotely since it is listening only on localhost.
- gitlab-monitor does not support modifying the listen port, so its metrics are not included.
Notes:
- Since Redis and Postgres are running in their own independent containers in this demo, additional configuration was required.
