This patch removes the baremetal virt driver from nova, which was
deprecated in Juno. It does not aim to perform any of the refactoring
we need to do now that the driver is gone, but is intended as a clean
removal of all the baremetal code itself.
Of specific note are the api_samples tests. We didn't have samples to
test the ironic proxy code, so I removed the baremetal ones for show
and index, resetting that extension back to "untested" status as if it
was new.
Tests that stub out ironic interactions and re-introduce those tests
should be added after this patch.

The nova-manage flavor sub-command was deprecated in Juno milestone-1
via commit a601556684 with a note that it
will be removed in Kilo.
This removes it.
Change I4e2399f2fbab2c20299dd62c104b9220c1d36fb2 is to remove the
related Tempest tests.

The syntax suggested for adding hooks to nova via setup.py entrypoints is:
entry_points = {
'nova.hooks': [
'resize_hook': your_package.hooks.YourHookClass,
]
},
But this is incorrect. The proper syntax for an entry_points entry is:
entry_points = {
'nova.hooks': [
'resize_hook=your_package.hooks:YourHookClass',
]
},

At the nova mid-cycle we agreed that while specs have made our blueprint
process significantly better, we think the current approach still leaves
much to be desired. This document is the outcome of the discussion at
the mid-cycle on how we want to manage blueprints in Kilo.
This proposal is being placed in devref, as we want to use gerrit's
workflow (two core reviews, inline comments, revisions etc) and this is
a document for developers.
Introduce the idea of project priorities.

This patch adds the basic NUMA filter that will take the proposed
instance topology and try to match it against that of a host.
The matching will be done in the following manner:
* Filter will try to match the exact NUMA cells of the instance to those
of the host. It *will not* attempt to pack the instance onto the host.
* It will consider the standard over-subscription limits for each cell,
and provide limits to the compute host accordingly.
* If instance has no topology defined, it will be considered for any host.
* If instance has a topology defined, it will be considered only for NUMA
capable hosts.

It turns out adding the specs requirement to blueprints adds a
non-trivial amount of overhead, revisit when a blueprint and spec is
needed to minimize overhead in cases where it isn't helpful.

Remove intersphinx from the docs build as it triggers network calls that
occasionally fail, and we don't really use intersphinx (links other
sphinx documents out on the internet)
This also removes the requirement for internet access during docs build.
This causes docs jobs to fail because we error out on warnings.

For some time, we've been informally implementing a "revert early"
policy around handling -2 worthy complaints after a patch has been
merged. These reverts can be contentious, so it's appropriate we make
it very clear what the policy and procedure here is in order to lessen
the contentiousness of these reverts.

Commit a507d42cf5 makes the

There is currently a misconception about how a patch gets merged:
Author proposes a patch, review team reviews it. Us, and Them. Instead
it should be a 'We.'
If the review bandwidth doesn't grow at the same rate as the patch
proposal rate then we end up with a massive backlog where people are
pinging cores for reviews.
Record a recommended policy of asking patch authors to offset the review
resources spent on their patch by reviewing other patches.

devref already contains a list of all modules, so no need to explicitly
include files that just contain lists of modules under the section 'Module
Reference'. Most of the deleted files are very outdated and refer to
non-existent modules anyway.
Leave services for now as it contains some content
that should be preserved. A later patch will clean those files up.
