Provide a kubernetes helm chart

[AntonOfTheWoods]

Problem
If wanting to self-host, kubernetes is a much more robust solution than docker compose.

Proposed solution
A helm chart to install all service deps for both local development and prod deployment:

• redis-compatible - there is no official chart but something like https://github.com/DandyDeveloper/charts/tree/master/charts/redis-ha or maybe https://github.com/OT-CONTAINER-KIT/redis-operator
• s3-compatible - either minio via the upstream helm chart or operator, or given that it has now been abandoned, something like garage and the garage operator https://github.com/rajsinghtech/garage-operator
• ingress/gateway traefik or maybe istio
• electric - local helm chart
• durable streams - local helm chart
• project servers - local helm chart

Alternatives considered
Docker compose.

Additional context
Docker compose is not needed at all, even for local dev. k3d and helm can be used to provide a fully-local, updates-on-file-change dev environment, without relying on developing in a container or other nasty bad DX solutions.

I can propose something for inclusion directly in this repo, if there is some interest.
