Fix positional arg swallow decorator

The update() method in the hosts extension is decorated with @check_host
but the function returned by decorator takes a kwarg which shadows the
'body' positional arg of the update() method.

i.e. if you call:

  controller.update(req, id, body)

then the body arg gets passed to the wrapper as its service kwarg and
never passed through to update(). We can see how the tests are all
passing body as a kwarg to avoid this.

Remove the service arg from check_host() but also from _list_hosts()
since the only place it is used is in the tests.

Avoid vm instance shutdown when power state is NOSTATE

Occasionally when nova uses libvirt lib to query hypervisor
xen the instance state of vm_power_state may end up
with a NOSTATE value. Existing code shuts down the instance
when we hit this state. Remove the check for NOSTATE
to avoid shutting down the instance.

Fixes LP #1085771.

Order instance faults by created_at and id.

It is possible that instance faults have the same created_at values so
ordering on that field alone is not deterministic. Add an additional
order by clause to order descending on id as well.

I am not sure if the order by exists to make tests pass; however,
without the additional "id" the tests do occasionally fail. See
http://logs.openstack.org/15078/18/check/gate-nova-python26/10709/console.html
for an example failure. If order does not actually matter we may want to
make the test smarter instead.

Use conductor for migration_get()

This patch removes direct database accesses for looking up
migrations by id, and instead queries conductor.

Fix network manager ipv6 tests.

When using a test runner that runs tests in a different order than
nosetests it is possible that IPv6AccountIdentiferTestCase tests run
before CommonNetworkTestCase. If this happens
IPv6AccountIdentiferTestCase sets the ipv6_backend to account_identifier
which causes the regexes in
CommonNetworkTestCase.test_get_instance_uuids_by_ipv6_regex to not
match.

Explicitly set the ipv6_backend to rfc2462 in CommonNetworkTestCase's
setUp() to ensure the regex's match the addresses in the fake network
DB.

Run test objectstore server on arbitrary free port

When tests are run under a test runner that runs tests concurrently
(like testr) failures can occur when two test processes attempt to
listen on the same port. Set the test objectstore server to use an
arbitrary free port when testing to avoid this problem.

Make ignore_hosts and force_hosts work again

Fixes bug 1087807

A recent refactor of scheduling filters and weights broke the
ignore_hosts and force_hosts functionality.  The refactored code would
have only worked if a list of host names (strings) were passed in to
host_manager's get_filtered_hosts().  Unfortunately that's what the unit
tests tested, but the real caller (filter_scheduler) actually passes a
list of HostState class instances.

Unit tests are fixed to pass HostStates and the offending code in the
host_manager has been fixed.
