DH parameter generation takes too much time:

    21:21:42 TASK [Generate DH Parameters (2048 bits)]
    21:21:42 task path: pilou-/ansible-role-burp/molecule/common/prepare.yml:9
    21:21:42 <molecule-burp-server> ESTABLISH kubectl CONNECTION
    [...]
    21:21:45 <molecule-burp-server> EXEC ['/usr/bin/kubectl', 'exec',
        '-i', 'molecule-burp-server', '--', '/bin/sh', '-c',
        "/bin/sh -c 'python3 ansible-tmp/AnsiballZ_openssl_dhparam.py && sleep 0'"]
    21:26:25 <molecule-burp-server> EXEC ['/usr/bin/kubectl', 'exec',
        '-i', 'molecule-burp-server', '--', '/bin/sh', '-c',
        "/bin/sh -c 'rm -f -r ansible-tmp/ > /dev/null 2>&1 && sleep 0'"]

quay.io/pilou/test:latest Docker image is the same that the one used for
default scenario.

/bin/kill is used in burp systemd unit

A new scenario using k8s based driver will be added, move all common
playbooks and config.

Workaround this error:

    TASK [tox : Install any sibling python packages] ***
    An exception occurred during task execution. To see the full traceback, use -vvv.
    The error was: command terminated with exit code 1
    fatal: [molecule]:

    }

With burp-2.1.32 (Debian Buster), ::1 is used even if ipv6 isn't
available resulting in this error:

    could not listen on address: ::1

in order to improve reusability. paths can still be used thanks to
the 'file' lookup.
