Pre-configured domains for projects and users
---------------------------------------------
ML2 plugin extension ``dns_domain_keywords`` provides same dns integration as
``dns_domain_ports`` and ``subnet_dns_publish_fixed_ip`` and it also allows to
configure network's dns_domain with some specific keywords: ``<project_id>``,
``<project_name>``, ``<user_id>``, ``<user_name>``. Please see example below for
more details.
* Create DNS zone. ``0511951bd56e4a0aac27ac65e00bddd0`` is ID of the project
used in the example

Special keywords ``<project_id>``, ``<project_name>``, ``<user_name>``
and ``<user_id>`` can be used in the network's, port's and floating IP's
``dns_domain`` attribute.
Those special keywords will be replaced by the corresponding data from the
request context.
With that cloud admin can define dns_domain for shared network and ports
which belongs to the other projects in the way that each project can use
separate DNS zones which needs to be pre-created by users.
To enable this feature ``dns_domain_keywords`` ML2 plugin extension has to
be enabled in the Neutron config.
Enabling multiple dns_integration extensions at the same time leads to an
error.
