Refactor to Deployments

move to rook style deployments, (away from statefulsets)

Hi @dmolik, can I ask what the motivation for moving away from StatefulSets is?

When I initially created this ticket, there was some significant talk around Valkey upgrade process, roll-backs and the need for better control. At the time it seemed that StatefulSet programming would get more in the way of granular deployment topology and Valkey upgrades.

I'll still need to split a Valkey cluster deployment into multiple deployment objects; Deployments or StatefulSets, but as far as fully switching to deployments; I'm up in the air.
