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.

'in' expresion matches substrings, therefore it is possible
that following expression will fail:
inventory_hostname in groups['groupname'][0]
for example when:
inventory_hostname = 'my-host-a'
groups['groupname'][0] = 'my-host-a1'
The result is running task on multiple hosts rather than single one.
Such action might result in playbook failure

Provide support for kolla dev mode in designate. When
'kolla_dev_mode' or 'designate_dev_mode' variables are
enabled, source code of designate project is cloned
and bindmounted.
