In Kolla Ansible OpenStack deployments, by default, libvirt is
configured to allow read-write access via an unauthenticated,
unencrypted TCP connection, using the internal API network.  This is to
facilitate migration between hosts.

By default, Kolla Ansible does not use encryption for services on the
internal network (and did not support it until Ussuri). However, most
other services on the internal network are at least authenticated
(usually via passwords), ensuring that they cannot be used by anyone
with access to the network, unless they have credentials.

The main issue here is the lack of authentication. Any client with
access to the internal network is able to connect to the libvirt TCP
port and make arbitrary changes to the hypervisor. This could include
starting a VM, modifying an existing VM, etc. Given the flexibility of
the domain options, it could be seen as equivalent to having root access
to the hypervisor.

Kolla Ansible supports libvirt TLS [1] since the Train release, using
client and server certificates for mutual authentication and encryption.
However, this feature is not enabled by default, and requires
certificates to be generated for each compute host.

This change adds support for libvirt SASL authentication, and enables it
by default. This provides base level of security. Deployments requiring
further security should use libvirt TLS.

Ironic has changed the default PXE to be iPXE (as opposed to plain
PXE) in Yoga. Kolla Ansible supports either one or the other and
we tend to stick to upstream defaults so this change enables
iPXE instead of plain PXE - by default - the users are allowed
to change back and they need to take one other action so it is
good to remind them via upgrade notes either way.

Ansible facts can have a large impact on the performance of the Ansible
control host. This patch introduces some control over which facts are
gathered (kolla_ansible_setup_gather_subset) and which facts are stored
(kolla_ansible_setup_filter). By default we do not change the default
values of these arguments to the setup module. The flexibility of these
arguments is limited, but they do provide enough for a large performance
improvement in a typical moderate to large OpenStack cloud.

In particular, the large complex dict fact for each interface has a
large effect, and on an OpenStack controller or hypervisor there may be
many virtual interfaces. We can use the kolla_ansible_setup_filter
variable to help:

    kolla_ansible_setup_filter: 'ansible_[!qt]*'

This causes Ansible to collect but not store facts matching that
pattern, which includes the virtual interface facts. Currently we are
not referencing other facts matching the pattern within Kolla Ansible.
Note that including the 'ansible_' prefix causes meta facts module_setup
and gather_subset to be filtered, but this seems to be the only way to
get a good match on the interface facts. To work around this, we use
ansible_facts rather than module_setup to detect whether facts exist in
the cache.

The exact improvement will vary, but has been reported to be as large as
18x on systems with many virtual interfaces.

For reference, here are some other tunings tried:

* Increased the number of forks (great speedup depending of the size of
  the deployment)
* Use `strategy = mitogen_linear` (cut processing time in half)
* Ansible caching (little speed up)
* SSH tunning (little speed up)

On machines with many cores, we were seeing excessive CPU load on systems
that were not very busy. With the following Erlang VM argument we saw
RabbitMQ CPU usage drop from about 150% to around 20%, on a system with
40 hyperthreads.

    +S 2:2

By default RabbitMQ starts N schedulers where N is the number of CPU
cores, including hyper-threaded cores. This is fine when you assume all
your CPUs are dedicated to RabbitMQ. Its not a good idea in a typical
Kolla Ansible setup. Here we go for two scheduler threads.
More details can be found here:
https://www.rabbitmq.com/runtime.html#scheduling
and here:
https://erlang.org/doc/man/erl.html#emulator-flags

    +sbwt none

This stops busy waiting of the scheduler, for more details see:
https://www.rabbitmq.com/runtime.html#busy-waiting
Newer versions of rabbit may need additional flags:
"+sbwt none +sbwtdcpu none +sbwtdio none"
But this patch should be back portable to older versions of RabbitMQ
used in Train and Stein.

Note that information on this tuning was found by looking at data from:

In services which use the Apache HTTP server to service HTTP requests,
there exists a TimeOut directive [1] which defaults to 60 seconds. APIs
which come under heavy load, such as Cinder, can sometimes exceed this
which results in a HTTP 504 Gateway timeout, or similar. However, the
request can still be serviced without error. For example, if Nova calls
the Cinder API to detach a volume, and this operation takes longer
than the shortest of the two timeouts, Nova will emit a stack trace
with a 504 Gateway timeout. At some time later, the request to detach
the volume will succeed. The Nova and Cinder DBs then become
out-of-sync with each other, and frequently DB surgery is required.

Although strictly this category of bugs should be fixed in OpenStack
services, it is not realistic to expect this to happen in the short
term. Therefore, this change makes it easier to set the Apache HTTP
timeout via a new variable.

An example of a related bug is here:

https://bugs.launchpad.net/nova/+bug/1888665

Whilst this timeout can currently be set by overriding the WSGI
config for individual services, this change makes it much easier.
