Follow up for I0c7e9a28876a1d4278fb2ed8555c2b08472864b9 which added a
ironic_enable_keystone_integration variable to support Ironic in
multi-region environments. This change skips Keystone service
registration based on ironic_enable_keystone_integration rather than
enable_keystone. It also updates the ironic-inspector.conf template to
use the new variable.

Config plays do not need to check containers. This avoids skipping
tasks during the genconfig action.
Ironic and Glance rolling upgrades are handled specially.
Swift and Bifrost do not use the handlers at all.

Including tasks has a performance penalty when compared with importing
tasks. If the include has a condition associated with it, then the
overhead of the include may be lower than the overhead of skipping all
imported tasks. In the case of the register.yml and bootstrap.yml
includes, all of the tasks in the included file use run_once: True.
The run_once flag improves performance at scale drastically, so
importing these tasks unconditionally will have a lower overhead than a
conditional include task. It therefore makes sense to switch to use
import_tasks there.
See [1] for benchmarks of run_once.

Including tasks has a performance penalty when compared with importing
tasks. If the include has a condition associated with it, then the
overhead of the include may be lower than the overhead of skipping all
imported tasks. For unconditionally included tasks, switching to
import_tasks provides a clear benefit.
Benchmarking of include vs. import is available at [1].
This change switches from include_tasks to import_tasks where there is
no condition applied to the include.

There are a number of tasks where we conditionally use include_tasks
with a condition, and the condition is always true. This change removes
these conditions, in preparation for switching unconditional task
includes to task imports.

Currently there are a few services that perform host configuration
tasks. This is done in config.yml. This means that these changes are
performed during 'kolla-ansible genconfig', when we might expect not to
be making any changes to the remote system.
This change separates out these host configuration tasks into a
config-host.yml file, which is included directly from deploy.yml.
One change in behaviour is that this prevents these tasks from running
during an upgrade or genconfig. This is probably what we want, but we
should be careful when any of these host configuration tasks are
changed, to ensure they are applied during an upgrade if necessary.

With Docker CE, the daemon sets the default policy of the iptables
FORWARD chain to DROP. This causes problems for provisioning bare metal
servers when ironic inspector is used with the 'iptables' PXE filter.
It's not entirely clear why these two things interact in this way,
but switching to the 'dnsmasq' filter works around the issue, and is
probably a good move anyway because it is more efficient.
We have added a migration task here to flush and remove the ironic-inspector
iptables chain since inspector does not do this itself currently.

When enable_ironic_ipxe is set in /etc/kolla/globals.yml,
the following happens:
- a new docker container, ironic_ipxe, is created. This contains
an apache webserver used to serve up the boot images
- ironic is configured to use ipxe

The Ironic templates and roles assume Keystone is enabled and they don't
make use of the `enable_keystone var. This patch changes the behavior so
that `noauth` is used as auth method for Ironic if keystone is not
enabled, the Ironic endpoint is not registered if keystone is not
enabled and the keystone section is not created in the config file.
