Bullet points shouldn't be preceded by a space. Doing so renders them as
blockquotes. We also have a load of literals/code. Mark them as such.

These are leftover from opendev migration and
without this fix the links results into Not Found.
Mainly need to use "src" in place of "tree" to
get these links working with opendev.org.
Also used git tags where line references are used
as branched references do not persist. And for line
references use #L in place of #n as that's where it
get's redirected.
Also update references for zuul and use of
devstack-vm-gate-wrap.sh in neutron functional jobs.

The quota driver ``ConfDriver`` was deprecated in Liberty release.
``NullQuotaDriver`` is created for testing although it could be used
in production if no quota enforcement is needed. However, because
the Quota engine is not plugable (is an extension always loaded), it
could be interesting to make it plugable as any other plugin.
This patch also creates a Quota engine driver API class that should be
used in any Quota engine driver. Currently it is used in the three
in-tree drivers implemented: ``NullQuotaDriver``, ``DbQuotaDriver``
and ``DbQuotaNoLockDriver``.

Closes-Bug: #1928211
This new quota driver, ``DbQuotaNoLockDriver``, does not create a lock
per (resource, project_id) but retrieves the instant (resource,
project_id) usage and the current (resource, project_id) reservations.
If the requested number of resources fit the available quota, a new
``Reservation`` register is created with the amount of units requested.
All those operations are done inside a DB transaction context. That
means the amount of resources and reservations is guaranteed inside
this transaction (depending on the DB backend isolation level defined)
and the new reservation created will not clash with other DB transation.
That will guarantee the number of resources and instant reservations
never exceed the quota limits defined for this (resource, project_id).
NOTES:
- This change tries to be as unobtrusive as possible. The new driver
uses the same ``DbQuotaDriver`` dabatase tables (except for
``QuotaUsage``) and the same Quota engine API, located in
``neutron.quota``. However, the Quota engine resources implements some
particular API actions like "dirty", that are not used in the new
driver.
- The Pecan Quota enforcement hooks,
``neutron.pecan_wgsi.hooks.quota_enforcement``, execute actions like
"resync", "mark_resources_dirty" or "set_resources_dirty", that has
no meaning in the new driver.
- The isolation between the Quota engine and the Pecan hook, and the
driver itself is not clearly defined. A refactor of the Quota engine,
Quota service, Quota drivers and a common API between the driver and
the engine is needed.
- If ``DbQuotaDriver`` is deprecated, ``CountableResource`` and
``TrackedResource`` will be joined in a single class. This resource
class will have a count method (countable) or a hard dependency on a
database table (tracked resource). The only difference will be the
"count" method implementation.

As per the community goal of migrating the policy file
the format from JSON to YAML[1], we need to do two things:
1. Change the default value of '[oslo_policy] policy_file''
config option from 'policy.json' to 'policy.yaml' with
upgrade checks.
2. Deprecate the JSON formatted policy file on the project side
via warning in doc and releasenotes.
Also replace policy.json to policy.yaml ref from doc and tests.

It's been four years since neutron.db.quota_db was changed
to really use neutron.db.quota.driver under the covers, let's
remove it now that all Openstack consumers have been updated.
There are other occurences besides below, but they are only
doc changes so will not be broken.

While the initial version of this patch removed neutron.db.api, a
different duplicate patch [1] landed first.
This patch cleans up the remining references to neutron.db.api
including those in the docs and comments.

This patch adds a blurb about the quota detail API extension to wrap
up the doc aspect of this feature.
