Prior to this patch, ML2/OVS and ML2/OVN had inconsistent IGMP
configurations. Neutron only exposed one configuration option for IGMP:
igmp_snooping_enabled.
Other features such as IGMP flood, IGMP flood reports and IGMP flood
unregistered were hardcoded differently on each driver (see LP#2044272
for a more details).
These hardcoded values has led to many changes over the years tweaking
them to work on different scenarios but they were never final because
the fix for one case would break the other.
This patch introduces 3 new configuration options for these other IGMP
features that can be enabled or disabled on both backends. Operators
can now fine tune their deployments in the way that will work for them.
As a consequence of the hardcoded values for each driver we had to break
some defaults and, in the case of ML2/OVS, if operators want to keep
things as they were before this patch they will need to enable the new
mcast_flood and mcast_flood_unregistered configuration options.
That said, the for ML2/OVS there was also an inconsistency with the help
string of igmp_snooping_enabled configuration option as it mentioned
that enabling snooping would disable flooding to unregistered ports but
that was not true anymore after the fix [0].

The ovn.ini file is a hold-over from the networking-ovn
tree. The docs all reference configuring OVN (and OVS)
options in ml2_conf.ini, so remove the old file and add
the neutron.ml2.ovn namespace to
etc/oslo-config-generator/ml2_conf.ini.

We had a number of code blocks that were being incorrectly rendered
inside block quotes, which messed with formatting somewhat. Correct
them. This was done using the following script:
sphinx-build -W -b xml doc/source doc/build/xml
files=$(find doc/build/xml -name '*.xml' -print)
for file in $files; do
if xmllint -xpath "//block_quote/literal_block" "$file" &>/dev/null; then
echo "$file"
fi
done
Note that this also highlighted a file using DOS line endings. This is
corrected.

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.

Extend neutron metering agent to generate Granular metering data.
The rationale here is to have data (bytes and packets) not just in
a label basis, but also in tenant, router, and router-label, and tenant-label
basis. This allows operators to develop more complex network monitoring
solutions.
Moreover, I added documentation to explain what is the neutron metering agent,
its configs, and different message formats.

The following changes are made for PDF document.
- Sample config/policy files are skipped for PDF doc build.
We hit several problems around verbatim of inline samples
in neutron, nova and others, so we decided to skip them now.
Downloadable links also should be avoided in PDF doc
as PDF doc is expected to work alone.
- tocdepth for latex is explicitly set to 3 for better navigation
in the generated PDF. The default was 1 and we cannot provide
enough information in PDF TOC.
- The module index is disabled as the neutron document does not
generate a full module index and it shows only partial entries.
'makeindex' and 'printindex' are set to empty in latex_elements.
The existing contents (mainly the top page) are reorganized a bit
for a better TOC of the generated PDF document:
- The top page of the documentation is simplified only with toctree
to avoid almost duplicated entries in the TOC of the PDF documentation.
The current TOC for PDF doc seems to use section titles as the first
level and title of linked pages as the second level. They are almost
same and the generated TOC would be redundant.
- The link to the API reference in the top page was moved
to a subdirectory so that PDF TOC can include it.
- 'Search' section is shown in index.rst only when the builder is 'html'
as this section uses a form and makes sense only for HTML doc.
