Operators can deploy their own scheduler filters. We currently provide
some minimal instructions for how to do this but it omits things like
the need to package these filters so they can be picked up correctly.

Added JSON schema defining `network_data.json` contents and
beefed up the MetadataTest functional test cases to use a
real instance instead of a database shell. This way the
tests see real data in the metadata service like a real
network_data.json.
Besides internal Nova consumption, this schema might be
helpful to other tools (such as ironic or Glean) to
validate human-generated `network_data.json` prior to
using it.

This adds two tests and updates the cross-cell resize docs to
show that _poll_unconfirmed_resizes can work if the cells are
able to "up-call" to the API DB to confirm the resize. Since
lots of deployments still enable up-calls we don't explicitly
block _poll_unconfirmed_resizes from processing cross-cell
migrations. The other test shows that _poll_unconfirmed_resizes
fails if up-calls are disabled.

When performing a resize, we'll want to (by default) select
target hosts from the source cell to do a traditional resize
if possible before considering target hosts in another cell
which will be slower and more complicated. If the source cell
is disabled or target flavor is not available in the source cell,
then we'll have no choice but to select a host from another cell.
But all things being equal between hosts, we want to stay within
the source cell (by default). Therefore this change adds a new
CrossCellWeigher and related configuration option to prefer hosts
within the source cell when moving a server. The weigher is
completely noop unless a cross-cell move is permitted by
configuration, which will be provided in a future change.

Yet another one of these. This time around, we make the following
changes:
- Put admin-focused stuff in '/admin', and user-focused docs in '/user'
- Merge the '/admin/quotas2' document into the '/admin/quotas' document
- Update references to novaclient to use openstackclient if possible and
include a TODO if not
- s/tenant/project/
Note that there is some duplication between the user and admin docs
here. That's necessary since, for example, showing a user's quotas is
also something an admin will want to do.

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)

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

We don't need to do a whole lot here. The key things to note are that
some host level configuration is now necessary, that the 'isolate' CPU
thread policy behaves slightly differently, and that you can request
'PCPU' inventory explicitly instead of using 'hw:cpu_policy=dedicated'
or the image metadata equivalent.

Track compute node inventory for the new MEM_ENCRYPTION_CONTEXT
resource class (added in os-resource-classes 0.4.0) which represents
the number of guests a compute node can host concurrently with memory
encrypted at the hardware level.
This serves as a "master switch" for enabling SEV functionality, since
all the code which takes advantage of the presence of this inventory
in order to boot SEV-enabled guests is already in place, but none of
it gets used until the inventory is non-zero.
A discrete inventory is required because on AMD SEV-capable hardware,
the memory controller has a fixed number of slots for holding
encryption keys, one per guest. Typical early hardware only has 15
slots, thereby limiting the number of SEV guests which can be run
concurrently to 15. nova needs to track how many slots are available
and used in order to avoid attempting to exceed that limit in the
hardware.
Work is in progress to allow QEMU and libvirt to expose the number of
slots available on SEV hardware; however until this is finished and
released, it will not be possible for nova to programatically detect
the correct value with which to populate the MEM_ENCRYPTION_CONTEXT
inventory. So as a stop-gap, populate the inventory using the value
manually provided by the cloud operator in a new configuration option
CONF.libvirt.num_memory_encrypted_guests.
Since this commit effectively enables SEV, also add all the relevant
documentation as planned in the AMD SEV spec[0]:
- Add operation.boot-encrypted-vm to the KVM hypervisor feature matrix.
- Update the KVM section of the Configuration Guide.
- Update the flavors section of the User Guide.
- Add a release note.

The conductor doc is not really end user material,
so this moves it under reference/, removes it from the
user page and adds it to the reference index for internals.
Also makes the contributor page link to the reference internals
since it's kind of weird to have one contributor section that
only mentions one thing but the internals under reference have
a lot more of that kind of detail. Finally, a todo is added so
we don't forget to update the reference internals about versioned
objects at some point since that's always a point of confusion
for people.

This adds support, in a new microversion, for specifying an availability
zone to the unshelve server action when the server is shelved offloaded.
Note that the functional test changes are due to those tests using the
"latest" microversion where an empty dict is not allowed for unshelve
with 2.77 so the value is changed from an empty dict to None.

We get questions about if it's possible to configure nova to
always use cinder for root volumes even if the user isn't
explicitly booting from volume. This change adds a FAQ entry
about that to the block device mappings docs and also suggests
a way to force users to use volume-backed servers using the
max_local_block_devices option. The config option help for that
option is also cleaned up since --image is a CLI option but we
should stick to REST API parameters in descriptions and the
default mentioned in the help already gets rendered by oslo.config.
Finally, a simple functional test is added to assert the workaround
mentioned in the docs.
