This is an example NVMe cleaner script that can listen to notifications
from a per-compute topic and perform basic NVMe (or generic command)
cleaning as a result.
It also supports periodic cleaning, notification pooling (if desired,
but not recommended), and single-shot (i.e. cron) mode.
I ran this while hammering my devstack node in a tight loop of create/
delete with a PCI device. The creates would succeed and fail as the
cleaning took a few seconds per iteration, then recover, create again,
delete, clean, etc. Dozens of loops in a row with expected results.

This adds support for devices that will be allocated to an instance
once and left in a reserved=total state. An external workflow can
put them back into allocatable state by dropping reserved back to
zero. Note this requires PCI-in-placement tracking for the affected
devices and it is only valid for type-PCI and type-PF devices.

This chnage adds the pre-commit config and
tox targets to run codespell both indepenetly
and via the pep8 target.
This change correct all the final typos in the
codebase as detected by codespell.

this mainly fixes typos in the tests and
one type in an exception message.
some addtional items are added to the dict based on
our usage of vars in test but we could remove them later
by doing minor test updates. They are intentionally not
fixed in this commit to limit scope creep.

this is the inital patch of applying codespell to nova.
codespell is a programing focused spellchecker that
looks for common typos and corrects them.
i am breaking this into multiple commits to make it simpler
to read and will automate the execution of codespell
at the end of the series.
