Change Ia1239069ccee39416b20959cbabad962c56693cf added support for
running a libvirt daemon on the host, rather than using the nova_libvirt
container. It did not cover migration of existing hosts from using a
container to using a host daemon.

This change adds a kolla-ansible nova-libvirt-cleanup command which may
be used to clean up the nova_libvirt container, volumes and related
items on hosts, once it has been disabled.

The playbook assumes that compute hosts have been emptied of VMs before
it runs. A future extension could support migration of existing VMs, but
this is currently out of scope.

In some cases it may be desirable to run the libvirt daemon on the host.
For example, when mixing host and container OS distributions or

This change makes it possible to disable the nova_libvirt container, by
setting enable_nova_libvirt_container to false. The default values of
some Docker mounts and other paths have been updated to point to default
host directories rather than Docker volumes when using a host libvirt
daemon.

This change does not handle migration of existing systems from using
a nova_libvirt container to libvirt on the host.

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.

While I8bb398e299aa68147004723a18d3a1ec459011e5 stopped setting
the net.ipv4.ip_forward sysctl, this change explicitly removes the
option from the Kolla sysctl config file. In the absence of another
source for this sysctl, it should revert to the default of 0 after the
next reboot.

A deployer looking to more aggressively change the value may set
neutron_l3_agent_host_ipv4_ip_forward to 0. Any deployments still
relying on the previous value may set
neutron_l3_agent_host_ipv4_ip_forward to 1.

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.

When OpenStack is deployed with Kolla-Ansible, by default there
are no durable queues or exchanges created by the OpenStack
services in RabbitMQ. In Rabbit terminology, not being durable
is referred to as `transient`, and this means that the queue
is generally held in memory.

Whether OpenStack services create durable or transient queues is
traditionally controlled by the Oslo Notification config option:
`amqp_durable_queues`. In Kolla-Ansible, this remains set to
the default of `False` in all services. The only `durable`
objects are the `amq*` exchanges which are internal to RabbitMQ.

More recently, Oslo Notification has introduced support for
Quorum queues [7]. These are a successor to durable classic
queues, however it isn't yet clear if they are a good fit for
OpenStack in general [8].

For clustered RabbitMQ deployments, Kolla-Ansible configures all
queues as `replicated` [1]. Replication occurs over all nodes
in the cluster. RabbitMQ refers to this as 'mirroring of classic
queues'.

In summary, this means that a multi-node Kolla-Ansible deployment
will end up with a large number of transient, mirrored queues
and exchanges. However, the RabbitMQ documentation warns against
this, stating that 'For replicated queues, the only reasonable
option is to use durable queues: [2]`. This is discussed
further in the following bug report: [3].

Whilst we could try enabling the `amqp_durable_queues` option
for each service (this is suggested in [4]), there are
a number of complexities with this approach, not limited to:

1) RabbitMQ is planning to remove classic queue mirroring in
   favor of 'Quorum queues' in a forthcoming release [5].
2) Durable queues will be written to disk, which may cause
   performance problems at scale. Note that this includes
   Quorum queues which are always durable.
3) Potential for race conditions and other complexity
   discussed recently on the mailing list under:
   `[ops] [kolla] RabbitMQ High Availability`

The remaining option, proposed here, is to use classic
non-mirrored queues everywhere, and rely on services to recover
if the node hosting a queue or exchange they are using fails.
There is some discussion of this approach in [6]. The downside
of potential message loss needs to be weighed against the real
upsides of increasing the performance of RabbitMQ, and moving
to a configuration which is officially supported and hopefully
more stable. In the future, we can then consider promoting
specific queues to quorum queues, in cases where message loss
can result in failure states which are hard to recover from.
