Monty Taylor 92d7d7caeb Fix W504 and remove exclusion
This is a topic where there are two points of view. While neither
is fundamentally better than the other in reality, what's best is
to not have any arguments about it. The tox.ini comments about 503
and 504 that were in place make the argument that:

  - 503 is intended to be disabled and 504 enabled by default
  - Donald Knuth believes 504 is the right way

Since Donald Knuth is smarter than all of us, align with 504, match
the comments in the file and turn on enforcement to keep it that way.

short_description: Create/Delete Bare Metal Resources from OpenStack
author: "Monty Taylor (@emonty)"
description:
- Create or Remove Ironic nodes from OpenStack.
options:
state:
description:
- Indicates desired state of the resource
choices: ['present', 'absent']
default: present
uuid:
description:
- globally unique identifier (UUID) to be given to the resource. Will
be auto-generated if not specified, and name is specified.
- Definition of a UUID will always take precedence to a name value.
name:
description:
- unique name identifier to be given to the resource.
driver:
description:
- The name of the Ironic Driver to use with this node.
required: true
chassis_uuid:
description:
- Associate the node with a pre-defined chassis.
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.
driver_info:
description:
- Information for this server's driver. Will vary based on which
driver is in use. Any sub-field which is populated will be validated
during creation.
suboptions:
power:
description:
- Information necessary to turn this server on / off.
This often includes such things as IPMI username, password, and IP address.
required: true
deploy:
description:
- Information necessary to deploy this server directly, without using Nova. THIS IS NOT RECOMMENDED.
console:
description:
- Information necessary to connect to this server's serial console. Not all drivers support this.
management:
description:
- Information necessary to interact with this server's management interface. May be shared by power_info in some cases.
required: true
nics:
description:
- 'A list of network interface cards, eg, " - mac: aa:bb:cc:aa:bb:cc"'
required: true
properties:
description:
- Definition of the physical characteristics of this server, used for scheduling purposes
suboptions:
cpu_arch:
description:
- CPU architecture (x86_64, i686, ...)
default: x86_64
cpus:
description:
- Number of CPU cores this machine has
default: 1
ram:
description:
- amount of RAM this machine has, in MB
default: 1
disk_size:
description:
- size of first storage device in this machine (typically /dev/sda), in GB
default: 1
capabilities:
description:
- special capabilities for the node, such as boot_option, node_role etc
(see U(https://docs.openstack.org/ironic/latest/install/advanced.html)
for more information)
default: ""
root_device:
description:
- Root disk device hints for deployment.
- See U(https://docs.openstack.org/ironic/latest/install/advanced.html#specifying-the-disk-for-deployment-root-device-hints)
for allowed hints.
default: ""
skip_update_of_masked_password:
description:
- Allows the code that would assert changes to nodes to skip the
update if the change is a single line consisting of the password
field.
- As of Kilo, by default, passwords are always masked to API
requests, which means the logic as a result always attempts to
re-assert the password field.
- C(skip_update_of_driver_password) is deprecated alias and will be removed in 2.14.
type: bool
default: 'no'
aliases: [ skip_update_of_driver_password ]
availability_zone:
description:
- Ignored. Present for backwards compatibility
requirements: ["openstacksdk", "jsonpatch"]
