  - Fix SSH transport for Ansible server

    with previous configuration of ansible server docker, as there was no
    ssh binary, ansible switched to paramiko and it was causing "cannot
    import name aead".

    Added "ssh" as binary and tried to make paramiko work as some modules
    requires it (such as PAN-OS). but it still fails with the same error...

    Also given "ansible-server" to ansible user as it can create
    PlaybooksTemp (wasn't allowed before).
