feature: run etcd on separate nodes

[Pionerd]

Summary

We're looking to build a setup that will receive a lot of traffic/load and for that we reason we're interested in deploying etcd on separate nodes (separate from the control plane) as described here: https://docs.rke2.io/install/server_roles

If I look at the current config.yaml.j2 I don't think this is currently supported, right?

I can make a PR to simply allow disabling certain roles in the config.yaml.j2, but maybe I'm overlooking another reason why this has not been built in yet. Any feedback is welcome.

Edit 8-Feb-25
Looks like this is going to be a bit more complicated than I thought because of all first_server logic. Ideas are welcome, I'm continuing to look into this.
