Configure centralized logging for all pods

[mattjmcnaughton]

Issue Currently, I can only access logs via kubectl logs. I'd like a more advanced logging aggregator/storage system.

Impl Most likely, I will use ElasticSearch/Kibana for logs. I will explore FluentBit as the forwarder.

Definition of Done

• [ ] All logs (application and Kubernetes) accessible in a central location, in a nicely formatted manner with the appropriate metadata.
• [ ] Brief blog post written describing my efforts.
