Fix race condition of resize confirmation

Currently, the db update of migration status is after the db update of
instance's vm_state in _finish_resize, so a race condition occurs when an
instance's vm_state is updated but the migration status doesn't, and at
this moment a resize confirmation is performed, then an exception
'MigrationNotFoundByStatus' is raised.

Extract image metadata from Cinder

This patch makes nova extract image metadata if it is present in the
volume dict received from Cinder API.

The volume image metadata is received from Cinder when the
volume_image_metadata Cinder extension is loaded.

This patch is part of the work done on blueprint improve-boot-from-volume
as this metadata will be used when booting instances from volumes
without the need to supply an image just for the metadata. Subsequent
patches will make Nova consider this metadata when booting instances
without and image id.

Add get_backdoor_port to consoleauth.

This adds a get_backdoor_port function to the consoleauth
service which enables returning the eventlet_backdoor port
from rpc for the service.

Add html reports to report action in coverage extension.

This makes a few minor cleanups and 2 additions to the
coverage extension. First, it adds a new optional field to the
report action: 'html'. This will generate an html report instead
of either the text or xml reports that the extension can
generate.

The second change is that it adds a return for the stop action.
Now upon successful completion of the stop action the directory
where the coverage data files will be returned.

Provide a configdrive helper which uses contextlib.

Eliminate race conditions in floating association

This makes associating and disassociating floating ips atomic and
idempotent. This means multiple concurrent messages will not leave
behind iptables rules and concurrent request will not cause odd
failures.

Fixes bug 1092762 and bug 1092761.

Enable nova exception format checking in tests.

Updates the Nova test runner so that it enables
'fatal_exception_format_errors' for testing.

Fixes a slew of issues in the tests including:
 -adds a whole bunch of missing kwarg's to exception constructors
 -removing an extra print statement in ec2/test_cloud
  (this was causing failures...)
 -removing a duplicate (and misnamed) flavor test case:
    test_remove_tenant_access_with_bad_access
 -removing an odd test case which tested throwing an exception with
  and without kwargs explicitly (the part testing without kwargs was
  removed)
 -explicitly update test/test_misc.py's test_exceptions_raise to disable
  formatting checks for now. This allows it to continue to pass.

Log last compute error when rescheduling.

When a scheduling attempt is re-tried, log the last exception from
the compute side.  The goal is to provide simpler access to debugging
information about why a build/resize is having issues.

Remove inconsistent usage of variable from hyperv.

Portions of the code use instance_name, while others use
instance['name']. In some cases, within the same function. See
lines 123, 153, and 156.

Ignore double messages to associate the same ip

Associating an ip removes the old association and adds a new one.
If we are already associated to the target ip, then we can avoid
sending extra messages and making db calls. The current possibility
of a double send contributes to bug 1092762.

Ensure datetimes can be properly serialized.

The nova-network manager was returning db models from methods invoked
via rpc.call(). These db models include non-primitive types that can
not be properly serialized (namely datetime objects). Use
to_primitive() to ensure that the data gets serialized properly.

Remove improper NotFound except block in list servers

Added a couple tests to verify that NotFound was actually
never raised when no results are returned from list servers
or list servers details, and then removed the except blocks
from the controller.
