Evaluate Redis Operators

As part of &557 we are looking into hosting Redis on Kubernetes. For this, we'll likely want to make use of a kubernetes operator that can automate some of the current toil surrounding provisioning, upgrades, resizes.

Criteria

• Operator is actively maintained
• Operator is production ready
• Operator supports Sentinel vs Redis cluster
• Operator supports custom images
• Operator supports custom redis config
