feat: improve cloudstack documentation

[devops-42]

Pull Request

What? (description)

• fixed typo in parameter userdata for virtual machine deployment
• changed IP address to use when accessing the talos API
• added second loadbalancerrule to enable communication with the Talos API (needed for bootstrapping the cluster)

Why? (reasoning)

The current documentation contains a typo for the userdata CLI parameter. When trying to bootstrap the cluster, that talosctlcould not reach the Talos API on the VM.

Acceptance

Please use the following checklist:

• you linked an issue (if applicable)
• you included tests (if applicable)

this looks like something specific to your environment, that you can't access the VMs directly?

[devops-42]

It's maybe Cloudstack specific: When using the offering for isolated networks the VM resides in a SDN which is not routed to the public network. I needed to add this rule in order to connect to the VM on the API port of Talos.

I don't know if that should be split out into a separate optional section (?).

Also if you do LB with external IP, Talos doesn't know about it, so it should be patched into the machine config, .machine.certSANs

[devops-42]

That would be a possibility. I made a PoC consisting of 3 CP and 2 Worker nodes in Cloudstack using the setup and could easily update the Kubernetes from 1.31.x to 1.32.x. I'll look into the patching of the machine config.
