Take the opportunity to clean up the docs quite a bit, ultimately
combining two disparate guides on the scheduler into one.

Alembic does lots of new things. Provide docs for how to use this. We
also improve upgrade docs slightly, removing references to ancient
reviews that are no longer really helpful as well as calling out our N
-> N+1 constraint.

Nested allocations are only partially supported in nova-manage placement
heal_allocations CLI. This patch documents the missing support and
blocks healing instances with VGPU or Cyborg device profile request in
the embedded flavor. Blocking is needed as if --forced is used with such
instances then the tool could recreate an allocation ignoring some of
these resources.

As a prerequisite for blueprint generic-mdevs we need to rename the
existing enabled_vgpu_types options and dynamically generated groups
into enabled_mdev_types.
There is no upgrade impact for existing users, as the original
options are still accepted.
NOTE(sbauza): As we have a lot of methods and objects named gpu-ish
let's just change what we need here and provide followups for
fixing internal tech debt later.

This beefy patch closes a long-standing TODO and allows us to move yet
more information out of the flavors guide and into specific documents.
This, combined with existing documentation in place, means we can remove
the sections for various extra specs from the 'user/flavors' guide:
- hw:cpu_realtime -> doc/source/admin/real-time.rst
- hw:cpu_realtime_mask -> doc/source/admin/real-time.rst
- hw:emulator_threads_policy -> doc/source/admin/cpu-topologies.rst
- hw:cpu_policy -> doc/source/admin/cpu-topologies.rst
- hw:cpu_thread_policy -> doc/source/admin/cpu-topologies.rst
- hw:cpu_sockets -> doc/source/admin/cpu-topologies.rst
- hw:cpu_cores -> doc/source/admin/cpu-topologies.rst
- hw:cpu_threads -> doc/source/admin/cpu-topologies.rst
- hw:cpu_max_sockets -> doc/source/admin/cpu-topologies.rst
- hw:cpu_max_cores -> doc/source/admin/cpu-topologies.rst

- hw:numa_mem.N -> doc/source/admin/cpu-topologies.rst
- hw:mem_page_size -> doc/source/admin/huge-pages.rst
Multiple improvements to the libvirt extra spec docs are included here,
for want of a better place to include them.

This patch adds the config option 'live_migration_scheme = tls' to the
secure live migration guide.
To let the live migration use the qemu native tls, some configuration of
the compute nodes is needed. The guide describes this but misses the
'live_migration_scheme' config option.
It is necessary to set 'live_migration_scheme' to tls to use the
connection uri for encrypted traffic. Without this parameter everything
seems to work, but the unencrypted tcp-connection is still used for the
live migration.

Introduce two new guides on UEFI and Secure Boot. In addition, update
the flavors guide to document the secure boot feature (though this doc
should really be removed in near term in favour of the auto-generated
docs, as noted inline).
Note that this change includes our first use of the ':nova:extra-spec:'
cross-reference role and highlights a small bug in that implementation.
This is resolved.

This hasn't been validated upstream and there doesn't appear to be
anyone using it. It's time to drop support for this. This is mostly test
and documentation damage, though there is some other cleanup going on,
like the removal of the essentially noop 'pick_disk_driver_name' helper.
