Add Support for creating Proxmox VM templates.

[mcbenjemaa]

Is your feature request related to a problem? Please describe.

We are using Proxmox to provision vanilla Kubernetes clusters.
and we also implementing a capi provider.

Although, we can use qemu provider to build images
But, I think automating the creation of proxmox templates is a way better.

Describe the solution you'd like
Having a Proxmox target that enables to create VM, boot from ISO, install stuff. and then stop it, and convert it to template.

Describe alternatives you've considered

packer proxmox builders can be used: https://developer.hashicorp.com/packer/plugins/builders/proxmox

build images manually with qemu.

Additional context
This can be achived via communicating with Proxmox API.
