Implement HA with Sentinel

[Sir-Jacques]

Hi, we're looking for a way to run Valkey HA. Previously we used the Bitnami chart with value snippet below, to run with a sentinel StatefulSet of 3 replicas.

valkey:
  architecture: replication
  sentinel:
    enabled: true

Are there any plans for implementing this? Or can the Valkey deployment in this new chart be ran HA (zero-downtime upgrades) in a different way?

If not I might be able to setup a PR, but I'll probably need some help.

Any updates on this?

Hi,

Is there an estimation when it will be done?

Looking forward to this as well. I feel like the 1.0 milestone is the tipping point for most people to transition away from the bitnami chart.

What's holding this back?

@khtee has some nice work in #137 , give it a review, so we can hopefully finally get this through.

Do we have a planned date for when this would be available?
