Update glance notification config on Icehouse

Red Hat bug https://bugzilla.redhat.com/show_bug.cgi?id=1087499
clarifies how we should be configuring notifications when not using the
legacy notifier_strategy configuration option.  This new configuration
isn't well documented so it was not clear from the get-go how to
proceed.  In summary:

- notifier_strategy should still be present but set to 'default' (this
  is extra important on Red Hat as they set this configuration to
  'qpid' in /usr/share/glance/glance-api-dist.conf)
- notification_driver should be messaging, messaging2, log, routing, or
  noop
- transport_url should be set

Regarding transport_url, I currently set to either 'qpid://' or
'rabbit://' but I believe you can do the full url such as
'rabbit://me:passwd@host:5672/virtual_host' which would eliminate the
need for a # of rabbit and qpid-related configurations.  We can clean
that bit up once we're sure this new configuration is in fact correct.

Fix incorrect transport property

The oslo.messaging library is expecting a property called transport_url
not transport_host. Because we are setting the notifier_strategy to
'default' without a valid transport oslo.messging does not know which MQ
driver to instantiate and it can instantiate Rabbit's even though the MQ
type might be QPID.

Remove explicit installation of python-anyjson

We previously had to force the installation of python-anyjson as
python-kombu was not pulling it in correctly (and this prevented
glance-api from starting), but the Red Hat team have since updated
python-kombu to properly depend upon python-anyjson.
