…g TF_VAR_xxx from env
The main usecase is to create mini cluster to test changes without creating new settings/xxx file.
The next example
TF_VAR_nodes_per_cluster=1 \
TF_VAR_node_size=S \
./labctl create --students 1 --settings settings/kubernetes.env --provider proxmox --tag container-training
will create 1 cluster on 1 node with S profile for hardware resource.

It's the first version working for only 1 student/cluster.
The code contains `TODO:` labels to remind some ideas for future
versions _( grep -r "TODO:" prepare-labs/terraform/*/libvirt)_
Running testing command on laptop:
TF_VAR_nodes_per_cluster=2 \
TF_VAR_node_size=S \
./labctl create \
--students 1 \
--settings settings/kubernetes.env \
--provider libvirt --tag container-training
To destroy , run
( TAG=container-training ; ./labctl destroy "$TAG" ; rm -f tags/"$TAG"/* )

This is the code for issue #685
I have done many tests to check vm creations and configurations then a test creating 3 nodes to run some commands from the slides :
All works well on my laptop running Archlinux with 4 CPU and 16GB of RAM ( it works on my laptop -> production 😄 )
The commit message shows the command lines and indicate the limitations.
Please to help.
