Devananda van der Veen d0e49e1b41 Documentation update
This patch contains several changes to the documentation which
were brought about by, initially, removing the webapi/v1 page and
replacing it with a link to the /api-ref/ page.

As I did that, I saw that our front page (index.html) needed to
be updated as well, and decided that the front page needed to
actually be completely rerwitten -- while preserving all the links.

Some of the TOC links from the front page were malformed because
subpages included more than one H1 heading, so I had to make small
changes in the api-audit-support and code-contribution-guide and
dev-quickstart pages, in order for the front page to render properly.

As I corrected the headings on dev-quickstart, I realized the page
was not comprehensively organized, and so decided to reorganize the
sections and make it easier to navigate.

Here is a bullet-point summary of this change:
* Major changes to content and organization of index page
* Moved the version history from webapi/v1 to dev/webapi-version-history
* Added API conceptual guide at dev/webapi
* Replaced webapi/v1 with a link to dev/webapi, in case anyone
  bookmarked it
* Removed doc references to webapi/v1
* Merged the pages dev/contributing and dev/code-contribution-guide
* Removed duplicate H1 headers in deploy/api-audit-support
* Reorganized and renamed section headers in dev/dev-quickstart,
  and made some substantive corrections and changes as well
* Updated wording at the top of the index and deploy/user-guide pages.

========================
REST API Version History
========================
**1.22**
Added endpoints for deployment ramdisks.
**1.21**
Add node ``resource_class`` field.
**1.20**
Add node ``network_interface`` field.
**1.19**
Add ``local_link_connection`` and ``pxe_enabled`` fields to the port object.
**1.18**
Add ``internal_info`` readonly field to the port object, that will be used
by ironic to store internal port-related information.
**1.17**
Addition of provision_state verb ``adopt`` which allows an operator
to move a node from ``manageable`` state to ``active`` state without
performing a deployment operation on the node. This is intended for
nodes that have already been deployed by external means.
**1.16**
Add ability to filter nodes by driver.
**1.15**
Add ability to do manual cleaning when a node is in the manageable
provision state via PUT v1/nodes/<identifier>/states/provision,
target:clean, clean_steps:[...].
**1.14**
Make the following endpoints discoverable via Ironic API:
* '/v1/nodes/<UUID or logical name>/states'
* '/v1/drivers/<driver name>/properties'
**1.13**
Add a new verb ``abort`` to the API used to abort nodes in
``CLEANWAIT`` state.
**1.12**
This API version adds the following abilities:
* Get/set ``node.target_raid_config`` and to get
``node.raid_config``.
* Retrieve the logical disk properties for the driver.
**1.11** (breaking change)
Newly registered nodes begin in the ``enroll`` provision state by default,
instead of ``available``. To get them to the ``available`` state,
the ``manage`` action must first be run to verify basic hardware control.
On success the node moves to ``manageable`` provision state. Then the
``provide`` action must be run. Automated cleaning of the node is done and
the node is made ``available``.
**1.10**
Logical node names support all RFC 3986 unreserved characters.
Previously only valid fully qualified domain names could be used.
**1.9**
Add ability to filter nodes by provision state.
**1.8**
Add ability to return a subset of resource fields.
**1.7**
Add node ``clean_step`` field.
**1.6**
Add :ref:`inspection` process: introduce ``inspecting`` and ``inspectfail``
provision states, and ``inspect`` action that can be used when a node is in
``manageable`` provision state.
**1.5**
Add logical node names that can be used to address a node in addition to
the node UUID. Name is expected to be a valid `fully qualified domain
name`_ in this version of API.
**1.4**
Add ``manageable`` state and ``manage`` transition, which can be used to
move a node to ``manageable`` state from ``available``.
The node cannot be deployed in ``manageable`` state.
This change is mostly a preparation for future inspection work
and introduction of ``enroll`` provision state.
**1.3**
Add node ``driver_internal_info`` field.
**1.2** (breaking change)
Renamed NOSTATE (``None`` in Python, ``null`` in JSON) node state to
``available``. This is needed to reduce confusion around ``None`` state,
especially when future additions to the state machine land.
**1.1**
This was the initial version when API versioning was introduced.
Includes the following changes from Kilo release cycle:
* Add node ``maintenance_reason`` field and an API endpoint to
set/unset the node maintenance mode.
* Add sync and async support for vendor passthru methods.
* Vendor passthru endpoints support different HTTP methods, not only
``POST``.
* Make vendor methods discoverable via the Ironic API.
* Add logic to store the config drive passed by Nova.
This has been the minimum supported version since versioning was
introduced.
**1.0**
This version denotes Juno API and was never explicitly supported, as API
versioning was not implemented in Juno, and **1.1** became the minimum
supported version in Kilo.
