Subject: [PATCH] Configure podman networks (#38)

* Add create podman network

This feature allow to use static IP in scenarios

* Add filter to IP of current node to prevent duplication in etc_hosts

* Fix published_ports by repeating the option instead of passing a list

* Add support for podman --detach option

* Add support for podman --ip option

* Reformat typo

The real purpose of this commit it to try to unlock the checks in
the github PR:
