This change simply extracts and slightly reorders the existing rescue
documentation from the reboot reference page.

While we do not have an automated fix for bug 1849479 this provides
a troubleshooting document for working around that issue where
allocations from a server that was evacuated from a down host need
to be cleaned up manually in order to delete the resource provider
and associated compute node/service.
In general this is also a useful guide for linking up the various
resources and terms in nova and how they are reflected in placement
with the relevant commands which is probably something we should
do more of in our docs.

Blueprint image-precache-support added a conf section called
[image_cache], so it makes sense to move all the existing image
cache-related conf options into it.
Old:
[DEFAULT]image_cache_manager_interval
[DEFAULT]image_cache_subdirectory_name
[DEFAULT]remove_unused_base_images
[DEFAULT]remove_unused_original_minimum_age_seconds
[libvirt]remove_unused_resized_minimum_age_seconds
New:
[image_cache]manager_interval
[image_cache]subdirectory_name
[image_cache]remove_unused_base_images
[image_cache]remove_unused_original_minimum_age_seconds

A blocker migration was added in Train [1] to force
deployments to make sure they have completed the
services.uuid online migration (added in Pike). Now
that we're in Ussuri we can drop that online data
migration code.
Note that InstanceListWithServicesTestCase is removed
because the scenario is now invalid with the blocker
DB migration.

in the resource tracker.

In Train [1] we deprecated support for compute drivers
that did not implement the update_provider_tree method.
That compat code is now removed along with the get_inventory
method definition and (most) references to it.
As a result there are more things we can remove but those
will come in separate changes.

When this patch [1] was introduced, it didn't take into consideration,
the updated/changed/modified parameters when using OSC vs nova CLI, so not
every option can be used in "openstack server create" which was used in "nova boot"
and vice versa. This bug would track reverting some of these incorrect commands usage.
For example- "nova boot --block device <params1>" can be translated as
"openstack server create --block-device-mapping <params2>" where params1 and
params2 are formatted differently (hence needs more than a simple search/replace)

The mentality of being able to continuously deliver nova
has been around since the beginning with Rackspace public
cloud trying to CD openstack as close to master as possible.
This has implications for how code series are structured,
reviewed and merged. For the most part this seems to be tribal
knowledge and we don't have anything very obvious in the nova
docs about it, and not all projects in openstack necessarily
subscribe to this mentality anymore, or do so grudgingly, but
it's worth documenting it in nova while still applied here.

The development policies section on code review was linking to the
generic openstack review guidelines but we have nova-specific
guidelines as well so this changes the policies page to link to the
nova code review guidelines, links the general guidelines into the
nova page, and also fixes a formatting issue in the nova code review
guidelines page.

If we're booting from an existing volume but the instance is not being
created in a requested availability zone, and cross_az_attach=False,
we'll fail with a 400 since by default the volume is in the 'nova'
AZ and the instance does not have an AZ set - because one wasn't requested
and because it's not in a host aggregate yet.
This refactors that AZ validation during server create in the API to
do it before calling _validate_bdm so we get the pre-existing volumes
early and if cross_az_attach=False, we validate the volume zone(s) against
the instance AZ. If the [DEFAULT]/default_schedule_zone (for instances) is
not set and the volume AZ does not match the
[DEFAULT]/default_availability_zone then we put the volume AZ in the request
spec as if the user requested that AZ when creating the server.
Since this is a change in how cross_az_attach is used and how the instance
default AZ works when using BDMs for pre-existing volumes, the docs are
updated and a release note is added.
Note that not all of the API code paths are unit tested because the
functional test coverage does most of the heavy lifting for coverage.
Given the amount of unit tests that are impacted by this change, it is
pretty obvious that (1) many unit tests are mocking at too low a level and
(2) functional tests are better for validating these flows.

using this feature.

This adds AggregateCacheNotification, related payload, and code in
conductor to emit this per-compute with progress information. This
also adds a "progress" phase to NotificationPhase, which allows for
start..progress..progress..end information for a single operation
(cache_images in this case).

This is a follow-up patch for https://review.opendev.org/676730.
In the TOC of the current PDF file [1], most contents related to
user and admin guides are located under "For Contributors" section.
This is weird. It happens because the latex builder constructs
the document tree based on "toctree" directives even though they
are marked as "hidden".
This commit reorganizes "toctree" per section.
The "toctree" directives must be placed at the end of
individual sections. Otherwise, content of a last section and
content just after "toctree" directive are concatenated
into a same section in the rendered LaTeX document.
This commit also improves the following as well:
* Specify "openany" as "extraclassoptions" to skip blank pages
along with "oneside" to use same page style for odd and even pages.
* Set "tocdepth" and "secnumdepth" to 3 respectively.
"tocdepth" controls the depth of TOC and "secnumdepth" controls
the level of numbered sections in TOC.
Note that this commit does not reorganize file structure under doc/source.
I believe this should be done separately.

These closely related features are the source of a disproportionate
number of bugs and a large amount of confusion among users. The spread
of information around multiple docs probably doesn't help matters.
Do what we've already done for the metadata service and remote consoles
and clean these docs up. There are a number of important changes:
- All documentation related to host aggregates and availability zones is
placed in one of three documents, '/user/availability-zones',
'/admin/aggregates' and '/admin/availability-zones'. (note that there
is no '/user/aggregates' document since this is not user-facing)
- References to these features are updated to point to the new location
- A glossary is added. Currently this only contains definitions for host
aggregates and availability zones
- nova CLI commands are replaced with their openstack CLI counterparts
- Some gaps in related documentation are closed

Thank God. The majority of the removed images are so crufty, it's
actually funny. I don't want to update them and it's unlikely anyone
else does either. The rest are just moved to be with their comrades in
the '_static/images' directory.
