    Force qemu emulation in CI and add dmidecode command to logs

    Some upstream infra is enabling nested virtualization but it's failing
    randomly so let's force qemu virt_type.

    We need it to debugs issues with jobs incorrectly detecting
    virtualization time.

    Fix rabbitmq configuration

    We can move to the commit hash for puppet-rabbitmq used in RDO queens, since
    this is what we are testing in RDO. This requires a few changes:

    - Update the URL used in the Puppetfile, and set the branch to 'master'.
    - Remove old workarounds in amqp.pp
    - Set loopback_users properly, based on what is requested by [1].

    [1] - https://github.com/voxpupuli/puppet-rabbitmq/commit/0ada399b330fbc84a1a1179ad0e827e0735e1912

    Also do below [Queens Only] changes to clear gate issues:-
    - Install PyYAML==3.12 as latest version has issues
      with older setuptools(22.0.5).
    - Install openstack modules from stable/queens rather
      than master.
