* Use source images
* Need to specify bash for &> syntax

Issues worked around:

* Manually configuring bridge via ip commands makes ifup fail to bring
  up the link. Adds a kayobe-network-bootstrap Zuul CI role that adds
  persistent configuration for the all-in-one network.

* bridge not active after interfaces role bounce. Added a pause, similar
  to https://github.com/michaelrigart/ansible-role-interfaces/pull/31

* fails installing docker python module for kolla user. WARNING: The
  repository located at mirror-int.ord.rax.opendev.org is not a trusted
  or secure host and is being ignored ERROR: No matching distribution
  found for docker===4.4.0 Adding trusted host for PyPI mirror.

* Tenks fails to create block devices - missing qemu-img (in qemu-utils)

* Tenks qemu emulator is different on Ubuntu

Remaining issues:

* Bare metal testing is unreliable on Ubuntu - some jobs see IPMI
  failures such as the following:

    ipmitool chassis bootdev pxe

    Error setting Chassis Boot Parameter 5\nError setting Chassis Boot
    Parameter 0\n

  Bare metal testing is disabled on Ubuntu for now.
