This change updates the NovaHWMachineType parameter to now default to the unversioned q35 machine type for x86_64 instances within a deployment. A simple environment file is also included to pin NovaHWMachineType to the previous versioned defaults during an upgrade to this release. Once upgraded operators can then use the following flow to record the machine type of existing instances allowing the default to eventually be changed: https://docs.openstack.org/nova/latest/admin/hw-machine-type.html This change depends on Ieb21fd8f3e895ea7611882f1e92f398efe2e77fa to ensure that the standalone role picks up this new default in CI. It also depends on Ia3f839a3c5e4e4b59898c11561fe7ef7126bba5f to ensure that all jobs use cirros 0.5.2 that includes the achi module now required when using q35 based instances. Depends-On: https://review.opendev.org/c/openstack/tripleo-quickstart-extras/+/785575 Finally, it also depends on I0e068043d8267ab91535413d950a3e154c2234f7 from Nova that is attempting to workaround a known QEMU issue that appears more prevalent when using this newer machine type.
