Add the ssh way which is neater than the proxmox ui.

Default ip is also now 192.168.100.199 which should be free

This provisions the storage node and for the first time, will trigger a puppet
run. This puppet run will install the storage's role including. Its network
paquets coming through the gateway to access everything.

We will build debian vms (oldstable/stable) from a template with some basis
already set-up to avoid repeating those actions for new provisioned vm.

This action is needed to be once in a while (every debian migration to new
stable for example). Still, this is worth documenting/scripting to ease
reproducibility.

This bunch of if...elif...fi is there to reproduce the way the
resource_group and nodename are currently built in the azure infra.

So that we can use those script instead of clicking in the portal ui.

We will either need to:

- factorize that snippet part at some point (which is duplicated in
  add-disk, create-vm and here so far)

- rename our resources in the azure portal

In regards to resource group, vm name computations.

Ideally, this should be factorized.

That'll avoid T1128 reiterating in the future...

We need that version because our manifests need it.
If not, the provisioning fails at the puppet run step.
