Allow controller extensions to extend update/show

This change allows controller extensions to define update and show
functions for a resource when the original controller does not
already do so.

create_db_entry_for_new_instance did not call sgh for default

When an instance is launched create_db_entry_for_new_instance() is
called which calls self.db.instance_create(). Then,
db.security_group_ensure_default() is called which creates the
default security group entry in the nova db. Though the sgh handler was
not called. Alternatively, if any nova secgroup-* call is made the sgh
is called which creates the default security group. This patch adds
a call to ensure_default() before db.instance_create() so the sgh
is called. Fixes a case missed in  bug 1050982

Fix network RPC API backwards compat

Commit d96102b6 bumped the RPC API version, but didn't handle backwards
compatibility correctly.

We need to retain support for the old 1.1 clients passing the original
set of kwargs - we can't rename kwargs, nor can we make new kwargs
required.

Allow group='foo' in self.flags() for tests.

Cells config options are in a 'cells' config group, and this is needed
to support the tests.

Do not alias stdlib uuid module as uuidutils, since nova has uuidutils.

A few tests use "uuid" as a local variable name, and so must alias the
Python stdlib uuid module to something else.  Unfortunately they chose
"uuidutils", but nova has a module called "uuidutils" so this is confusing.
So change "uuidutils" to "stdlib_uuid" to reduce confusion.

Move nova shared config options to nova.config

This strips nova.flags down to be left just for backwards compatibility
with add-ons importing nova.flags and using nova.flags.FLAGS

Remove nova.flags imports from bin/*

nova.flags is no longer needed except to load nova config options shared
across multiple daemons.

This removes nova.flags from the bin programs and makes sure that
nova.flags is imported in nova.config for now.

Remove importing of flags from compute/*

Remove nova.flags imports from scheduler code

Removes FLAGS and LOG from baremetal_host_manager completely, which
doesn't use them.

Adds support for ConfigDriveV2 in Hyper-V

Supports iso9660 ConfigDriveV2 drives, which can be attached to the
instance on boot as VHD or ISO.
Admin password injection can be selectively enabled for security concerns.

Updates also the hyperv tests.

Adds documentation for Hyper-V testing

The Hyper-V Nova Compute plugin uses Windows Management Instrumentation
(WMI) as the main API for hypervisor related operations.
WMI has a database / procedural oriented nature that can become difficult to
test with a traditional static mock / stub based unit testing approach.

This document explains the architecture of the implemented infrastructure.
