Revert "Whitelist external netaddr requirement"

This reverts commit de59c55e77ead72df42c0445c09cf4d63131f6bd.

The netaddr developers have agreed to go back to uploading releases
to PyPI, so this workaround is no longer necessary. For details see
https://github.com/drkjam/netaddr/issues/57#issuecomment-31796111 .

Enable compute_node_update to tolerate deadlocks

When running the CI there were cases when the aformentioned method would
throw a DBDeadlock exception.

Ignore duplicate delete requests

Stop delete requests from queueing up in the compute manager if the
task_state is already set to DELETING. This prevents exhausting thread
pools when the service is stuck on a lock/external request.

Dealing with delete requests that never got executed is not in scope of
this change and will be submitted separately.

Cleanup 'deleting' instances on restart

In case some instance was marked as deleting but for some reason didn't
finish (for example request was stuck in libvirt), retry the delete at
startup. This happens at startup and on the host owning the instance,
so there's no reason to use the lock.

Add API schema for v3 multinic API

By defining the API schema, it is possible to separate the validation
code from the API method. The API method can be more simple.
In addition, a response of API validation error can be consistency for
the whole Nova API.

Partially implements blueprint nova-api-validation-fw

remove redundant __init__() overwriting when getting ExtensionResources

As described in #1266344, some of child class in
<nova>/nova/api/openstack/compute/contrib/ has overwrited __init__()
without specified needs. Removing that could help keeps codes clean and
consistent (nearly all others don't overwrite __init__()).

Add explicit discussion of dependencies to README.rst

Noted that building the documentation has more dependencies
than merely running Nova.
Noted that the standard development environment is sufficient.
Noted that the standard runtime environment plus oslo.sphinx
is sufficient.

Small edits on help strings

These were initially noted during import into the manuals at
https://review.openstack.org/67502

Fixes include rework of text, missing or extra spaces, wrong
capitalization and no sentence style capitalization.

A hacking check has been added that tests that all config options
start with a capital letter.

Additional check for qemu-nbd hang

/sys/block/*device*/pid check is not enough. I see that the unix
socket used by the device my be stuck as well, so let's add another
check for the path to the unix socket for the device as well to
figure out if the device is free. Complain loud and clear that the
qemu-nbd is leaking resources.
