Integrate clickhouse-backup to helm chart

Hey,
I was looking for the ways to implement automatic backup of my data stored in Clickhouse and found out that there is already a super cool tool from Altinity: https://github.com/Altinity/clickhouse-backup.

However, it's presented only in a view of of Docker container but there is no out-of-box way to integrate it to existing helm chart, only through patching the helm chart itself by adding a sidecar container.

Is there is a way to integrate this tool to existing helm chart? This could be a separate feature. So all values will be passed through values.yaml, etc.

Or maybe there are some workaround that we can use for creating a automatic backups creation tool?

Thanks!
