Devananda van der Veen 6e82b2118a Update the api-ref documentation for Root and Nodes 
This updates the API root documentation, which was non-existent,
and the Node documentation significantly, replacing many of the samples
and adding more verbiage to each property.

It's not perfect, but this is vastly more correct than the current docs.

=============
Nodes (nodes)
=============
List, Searching, Creating, Updating, and Deleting of bare metal Node resources
are done through the ``/v1/nodes`` resource. There are also several sub-resources,
which allow further actions to be performed on a bare metal Node.
A Node is the canonical representation of a discretely allocatable server,
capable of running an Operating System. Each Node must be associated with a
``driver``; this informs Ironic what protocol to use when managing the Node.
Beginning with API microversion 1.6, a Node may be referenced both by its UUID
and by a unique human-readable "name" in any request. Throughout this
documentation, this is referred to as the ``node_ident``. Responses clearly
indicate whether a given field is a ``uuid`` or a ``name``.
Create Node
===========
.. rest_method:: POST /v1/nodes
Creates a new Node resource.
This method requires that a ``driver`` be supplied in the request body. Most
subresources of a Node (eg, ``properties``, ``driver_info``, etc) may be
supplied when the Node is created, or the resource may be updated later.
API microversion 1.2 introduced the new ``available`` state name, which replaced
``None`` as the status of an unprovisioned Node. All clients should be updated to
use the new ``available`` state name.
Nodes in the ``available`` state may have workloads provisioned on them; they are
"available" for use.
API microversion 1.11 changed the default initial state of newly-created Nodes
from ``available`` to ``enroll``. This provides users a workflow to verify the
manageability of a Node and perform necessary operational functions (eg, building
a RAID array) before making the Node available for provisioning.

Request
-------
.. rest_parameters:: parameters.yaml
- driver: r_driver_name
**Example Node creation request:**
.. literalinclude:: samples/node-create-request.json
:language: javascript
Response
--------
The response will contain the complete Node record, with the supplied data,
and any defaults added for non-specified fields. Most fields default to "null"
or "".
API microversion 1.5 introduced the ``name`` field.
API microversion 1.7 introduced the ``clean_step`` field`
API microversion 1.12 introduced support for the ``raid_config`` and
``target_raid_config`` fields.
The list and example below are representative of the response as of API microversion 1.16.

List Nodes
==========
.. rest_method:: GET /v1/nodes
Return a list of bare metal Nodes, with some useful information about
each Node. Some filtering is possible by passing in flags with the request.
By default, this query will return the name, uuid, instance uuid, power state,
provision state, and maintenance setting for each Node.
API microversion 1.8 added the ``fields`` Request parameter. When specified,
this causes the content of the Response to include only the specified fields,
rather than the default set.
API microversion 1.9 added the ``provision_state`` Request parameter, allowing
the list of returned Nodes to be filtered by their current state.
API microversion 1.16 added the ``driver`` Request parameter, allowing
the list of returned Nodes to be filtered by their driver name.

List Nodes Detailed
===================
.. rest_method:: GET /v1/nodes/detail
Return a list of bare metal Nodes with complete details. Some filtering is
possible by passing in flags with the request.
This method is particularly useful to locate the Node associated to a given
Nova instance, eg. with a request to ``v1/nodes/detail?instance_uuid={NOVA INSTANCE UUID}``

Show Node Details
=================
.. rest_method:: GET /v1/nodes/{node_ident}
