Redis 7.4 support

[deefdragon]

Redis released Version 7.4 a few months ago. One of the big things they added was hash subkey expiration, which I have taken advantage of in my code. Unfortunatly, no 7.4 image exists for usage with the operator.

As an asside, I did just go and build a V7.4.0 on my own, and deploy it in my environment and it appears to work fine. (well, fine as in there are no extra errors I'm getting as compared to the 7.2 tag I was working with. I'm still getting errors, but that's due to the Operator being in beta, and clustering being hard.)

@deefdragon What error are you getting can you paste them here

Issues akin to the ones I mentioned in this bug on the operator tracker. Specifically that if a node disconnects, it never reconnects to the cluster and is just stuck there dangling.

I've had to completely nuke and reconstruct the cluster several times now after different events (like power-losses) have brought down my infra, causing the nodes to no longer act as a single cluster. The nodes just dont recognize they are disconnected from oneanother, and the operator doesen't do anything to attempt to fix things in that case.

The only actual error I get is something like CLUSTERDOWN Hash slot not served on the querying application.
