kevin 330f8613ee Create config_template plugin
The change introduces the `config_template` plugin within our ansible
source tree with the intention to replace the `copy_update` module with
a proper ansible action plugin.

The new module implements a method to overwrite and add items into
configuration files without the need to specify all items in templates
as default variables.

The plugin currently supports ini, json, and yaml files and can be
a drop in replacement for the current template and copy_update
usage as it pertains to the various configuration files that we need
for OpenStack.

Partially implements: blueprint tunable-openstack-configuration

module: config_template
version_added: 1.9.2
short_description: Renders template files providing a create/update override interface
description:
- The module contains the template functionality with the ability to override items
in config, in transit, though the use of an simple dictionary without having to
write out various temp files on target machines. The module renders all of the
potential jinja a user could provide in both the template file and in the override
dictionary which is ideal for deployers whom may have lots of different configs
using a similar code base.
- The module is an extension of the **copy** module and all of attributes that can be
set there are available to be set here.
options:
src:
description:
- Path of a Jinja2 formatted template on the local server. This can be a relative
or absolute path.
required: true
default: null
dest:
description:
- Location to render the template to on the remote machine.
required: true
default: null
config_overrides:
description:
- A dictionary used to update or override items within a configuration template.
The dictionary data structure may be nested. If the target config file is an ini
file the nested keys in the ``config_overrides`` will be used as section
headers.
config_type:
description:
- A string value describing the target config type.
choices:
- ini
- json
- yaml
