[2.23] Fix calico-node in etcd mode (#10768)

* CI: Document the 'all-in-one' layout + small refactoring (#10725)

* Rename aio to all-in-one and document it

ADTM.
Acronyms don't tell much.

* Refactor vm_count in tests provisioning

* Add test case for calico using etcd datastore (#10722)

* Add multinode ci layout

* Add test case for calico using etcd datastore

* Fix calico-node in etcd mode (#10438)

* Calico : add ETCD endpoints to install-cni container

* Calico : remove nodename from configmap in etcd mode
