libvirtd was being restarted on the controller during negative
evacuation tests that rely on the service being to cause an
evacuation failure.
This change adds various virt services to the list of services stopped
and now disabled on the host to ensure these don't cause systemd to
restart libvirtd:
* virtlogd.service
* virtlogd-admin.socket
* virtlogd.socket
* virtlockd.service
* virtlockd-admin.socket
* virtlockd.socket

The recent switch to Focal introduced a change in behaviour for the
libvirtd service that can now be restarted through new systemd socket
services associated with it once stopped. As we need it to remain
stopped during the initial negative evacuation tests on the controller
we now need to also stop these socket services and then later restart
them.

This change reworks the evacuation parts of the original
nova-live-migration job into a zuulv3 native ansible role and initial
job covering local ephemeral and iSCSI/LVM volume attached instance
evacuation. Future jobs will cover ceph and other storage backends.

This changes the nova-multi-cell job to essentially
force cross-cell resize and cold migration. By "force"
I mean there is only one compute in each cell and
resize to the same host is disabled, so the scheduler
has no option but to move the server to the other cell.
This adds a new role to write the nova policy.yaml file
to enable cross-cell resize and a pre-run playbook so
that the policy file setup before tempest runs.

For the most part this should be a pretty straight-forward
port of the run.yaml. The most complicated thing is executing
the post_test_hook.sh script. For that, a new post-run playbook
and role are added.
The relative path to devstack scripts in post_test_hook.sh itself
had to drop the 'new' directory since we are no longer executing
the script through devstack-gate anymore the 'new' path does not
exist.
