Add support for `--cluster_announce_ip`

[applike-ss]

When using cluster_mode emulated it makes sense to set the --cluster_announce_ip (maybe in native mode as well?).

I would like to see this supported in the operator. It might break client libraries to not have this set up for e.g. the java library lettuce (see: https://github.com/redis/lettuce/issues/1736).

I assume it should be easy to set up from within the operator using POD_IP references?

Hey,

For your specific usecase, Why can't you pass the --cluster_announce_ip arguement directly from the args field in the Dragonfly CR? We dont have plans to support cluster mode in Dragonfly Operator in the near future.

For setting a cluster announce ip i would need to know this ip, however it would be the ip of the service that the dragonfly operator creates. So it is unknown prior creation of the CR
