Add podman network options to support use of static IP addresses

[laurent-indermuehle]

This pull request adds Podman network options that allow usage of static IP in containers.

With the following molecule.yml you can write scenarios that tests communication between containers without relying on complicated DNS setup:

platforms:

  - name: node1
    registry: &redhat {url: registry.access.redhat.com}
    image: &image ubi8/ubi-init
    tmpfs: &tmpfs ['/run', '/tmp']
    volumes: &volumes ['/sys/fs/cgroup:/sys/fs/cgroup:ro']
    capabilities: &capabilities ['SYS_ADMIN', 'NET_ADMIN']
    command: &command "/usr/sbin/init"
    security_opts: &security_opts ['label=disable']
    network: &network setup_dedicated
    subnet: &subnet '10.90.0.0/16'
    etc_hosts: &etc_hosts
      "node1": "10.90.0.101"
      "node2": "10.90.0.102"
    ip: 10.90.0.101

  - name: node2
    registry: *redhat
    image: *image
    tmpfs: *tmpfs
    volumes: *volumes
    capabilities: *capabilities
    command: *command
    security_opts: *security_opts
    network: *network
    subnet: *subnet
    etc_hosts: *etc_hosts
    ip: 10.90.0.102
    

It is impossible to change the /etc/hosts file on a running container. This is why I edited the create.yml Playbook to add this feature.

Closing to try to relaunch the checks

[laurent-indermuehle]

Nothing I did, helped rerun the checks. Maybe it's because Github-action says "This scheduled workflow is disabled because there hasn't been activity in this repository for at least 60 days."?
Anyway, I fixed a conflict in my branch and now it should be safe to merge.

Closing because Github-actions seems stuck. Will repopen.
