Logging - Add ability for cloud-native backups to Elastic via Cronjob
Feature Request
Why
There isn't currently a way to natively back-up elastic indices to cloud backends.
Proposed Solution
Following these docs: https://www.elastic.co/guide/en/cloud-on-k8s/0.9/k8s-snapshot.html
- Build a BB-based Elastic image with the necessary cloud plugins inside of it and reference this image in logging chart.
- Add a flag to enable a back-up cronjob.
- Make the cronjob configurable.
- Cron schedule
- Customizable script (in the event for targeted back-ups)
