This commit removes the previous limitation on the number of tenants
that can be filtered using the `filter_tenant_id` aggregate property
in the AggregateMultitenancyIsolation scheduler filter.
The `filter_tenant_id` can now be used as a suffix, allowing for an
unlimited number of tenant ID properties to be set on the
aggregate. This update maintains backward compatibility.

This change mainly fixes incorrect use of backticks
but also adress some other minor issues like unbalanced
backticks, incorrect spacing or missing _ in links.
This change add a tox target to run sphinx-lint
as well as adding it to the relevent tox envs to enforce
it in ci. pre-commit is leveraged to install and execute
sphinx-lint but it does not reqiure you to install the
hooks locally into your working dir.

That's one giant hole in our docs. Whoops.

Despite having a NumInstancesFilter, we miss a weigher that would classify hosts
based on their instance usage.

This change remvoes the az filter and always enabled
the placement pre-filter. As part of this removal
the config option to control enabling the pre-filter
is removed as it is now mandatory.
The AZ filter docs and tests are also removed and an upgrade
release note is added.

This change updates the cpu and ram initial
allocation ratios to 4.0 and 1.0 to reflect
the typical values that are suitable for non web
hosting workloads.

The PowerVM driver was deprecated in November 2021 as part of change
Icdef0a03c3c6f56b08ec9685c6958d6917bc88cb. As noted there, all
indications suggest that this driver is no longer maintained and may be
abandonware. It's been some time and there's still no activity here so
it's time to abandon this for real.
This isn't as tied into the codebase as the old XenAPI driver was, so
removal is mostly a case of deleting large swathes of code. Lovely.

Custom filters are still supported. Custom schedulers / scheduler
drivers are what is not. This patch fixes the wording.

A recent customer call highlighted some misunderstandings about the two
weighers in the nova tree. Firstly, the basis for the metrics used by
the 'IoOpsWeigher' was not well explained and required some spelunking
through the code to understand. Secondly, the 'BuildFailureWeigher'
multiplier, configured by '[scheduler] build_failure_weight_multiplier',
defaults to a very large value for reasons that are not apparent unless
you read the commit logs for that weigher (hint: it's because we wanted
to preserve the behavior of the older filter-based approach to handling
nodes with build failures). Expand the documentation to fill both gaps.
In the process, we also correct some small nits with this doc, mostly
centered around whitespace.

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