Jenkins 2a9d49d9bc Add cookiecutter-generated files for project
Use cookiecutter (https://git.openstack.org/openstack-dev/cookiecutter)
to generate config for tox so we can generate docs, run pep8, etc.
Also move CONTRIBUTING.rst to the root of the repository in keeping
with what seems to be the standard location. This move allows us to
easily generate the docs. Also include a tiny fix to allow pep8 to
run cleanly.

short_description: Activate/Deactivate Bare Metal Resources from OpenStack
extends_documentation_fragment: openstack
description:
- Deploy to nodes controlled by Ironic.
options:
state:
description:
- Indicates desired state of the resource
choices: ['present', 'absent']
default: present
deploy:
description:
- Indicates if the resource should be deployed. Allows for deployment
logic to be disengaged and control of the node power or maintenance
state to be changed.
choices: ['true', 'false']
default: true
uuid:
description:
- globally unique identifier (UUID) to be given to the resource.
required: false
default: None
ironic_url:
description:
- If noauth mode is utilized, this is required to be set to the
endpoint URL for the Ironic API. Use with "auth" and "auth_type"
settings set to None.
required: false
default: None
config_drive:
description:
- A configdrive file or HTTP(S) URL that will be passed along to the
node.
required: false
default: None
instance_info:
description:
- Definition of the instance information which is used to deploy
the node. This information is only required when an instance is
set to present.
image_source:
description:
- An HTTP(S) URL where the image can be retrieved from.
image_checksum:
description:
- The checksum of image_source.
image_disk_format:
description:
- The type of image that has been requested to be deployed.
power:
description:
- A setting to allow power state to be asserted allowing nodes
that are not yet deployed to be powered on, and nodes that
are deployed to be powered off.
choices: ['present', 'absent']
default: present
maintenance:
description:
- A setting to allow the direct control if a node is in
maintenance mode.
required: false
default: false
maintenance_reason:
description:
- A string expression regarding the reason a node is in a
maintenance mode.
required: false
default: None
requirements: ["shade"]
