We still see flakiness when downloading content from Ansible Galaxy,
often HTTP 520. This change increases the retries from 3 to 10, and adds
a 5 second delay between attempts.

The 'openstack server show <server> -f value -c addresses' command
previously had output like this:

    <network name>=<IP>

Now it shows a Python output like this:

    {'<network name>': ['IP']}

This broke the parsing of the command output when determining which IP
address to use to access a bare metal instance via SSH.

This change fixes the issue by querying the server's port in Neutron,
and using the fixed IP address.

Update Apt cache prior to all package installation tasks.

Adds apt_cache_valid_time, which defaults to 3600 seconds. This allows
the time for which the Apt cache is valid to be configured.

* 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.

This partially reverts commit 47bbb96b
which triggered a retry on vexxhost clouds.

The issue was introduced in Ie8fd965165e8d347d27528a2c16d0647e412ccdc,
which applied some fixes for CentOS 8.3, and inadvertently removed
the Tenks variable that forces the use of qemu for 'bare metal' VMs.
This lead to autodetection of KVM, which does not work well when nested
in all CI cloud providers.

This change fixes the issue by forcing the use of qemu for the overcloud
once more. It also adds a similar option for the seed VM job.

It's now possible to change Docker's default 64M SHM size

Jobs that test baremetal deployment are currently failing when run on
Vexxhost infrastructure. The seed VM job also has trouble on Vexxhost,
although does sometimes pass. It's not clear why yet, and we are still
investigating. Until we have a solution, fail in the pre phase when we
land on vexxhost clouds, in order to trigger the zuul retry mechanism.

Also use the normal number (5) of attempts for upgrade jobs, since these
no longer deploy the previous release in the pre phase.

Finally, incorporate a fix from
https://review.opendev.org/c/openstack/kayobe-config-dev/+/777076 to
allow this to merge. This part can be reverted once the
kayobe-config-dev patch merges.
