Since Ansible 2.x introduces safer handling when deploying Python scripts/modules in combination with become/become_user, it is necessary to introduce changes to both Molecule configuration and to document this requirement somewhere.

The "problem" is that some of the roles utilise become/become_user combination, and in case the SSH connection is not established via root user, failures will happen due to Ansible being unable to change ownership of copied-over module/Python scripts (see above link for more details).

The following should be done:

• Update all Molecule configurations to include the following snippet:

  ansible:
    ansiblecfg_ssh_connection:
      pipelining: True

• Document the use of become/become_user combo in roles and make the user aware of implications and possible solutions (by at least linking to the official project explanation).

• Usage instructions should be updated to mention this explicitly somewhere at the top, as well as to include pipelining configuration in ansible.cfg.
