Adds Config Drive Support

Previously, nova did not support forcing config_drive
and users would need to specify the config-drive=true
nova CLI option.  However, Horizon G release is unable
spawn instances using the config-drive=true CLI option.
This change provides the ability for users to fully leverage
config_drive for Nova deployments.

More information on Config Drive can be found here:
  http://http://docs.openstack.org/trunk/openstack-compute/admin/content/config-drive.html

The change implements a new force_config_drive parameter.
The parameter is set to false to maintain backwards compatability.

Adds support for RabbitMQ Clustering

Prior to this change, only a single RabbitMQ Broker
could be deployed by the nova::rabbitmq class.

that can enable RabbitMQ clustering.

Defaults to false for backwards compatibility.

Update rabbitmq dependency

This commit updates the revision of rabbitmq to install for testing.

This revision was chosen for two reasons:

- later revisions remove the rabbitmq::server class
- later revisions do not support installing from your local distro (which
means you will likely get a version not tested with openstack)

Pin rabbit and mysql to major version for fixtures

Previously, unit tests were using master for testing.

This commit changes them to use the newly created major version
branches. This allows us to backport bug fixes while we wait for
upstream to stabilize.

Adds Support for X-Forwarded-For HTTP Headers

Previously, the nova::api class did not support proxies and
load-balancers that use X-Forwarded-For Headers to identify the
originating IP address of requests.  This change implements the
use_forwarded_for parameter to enable/disable the ability for
Nova API to treat the X-Forwarded-For HTTP Header as the canonical
remote address.

Defaults to false for backwards compatibility and to disable
X-Forwarded-For Headers.

Update allowed_hosts conditional statement

In the origin nova::db::mysql, if the value of $allowed_hosts
contains or equals to $host, then puppet will complain duplicate
declaration error. This patch is aim to update the allowed_hosts
conditonal statement in nova::db::mysql.

There are two cases to pass $allowed_hosts to $real_allowed_hosts:

   - If $allowed_hosts is array,then remove $host from $allowed_hosts;
   - elsif $allowed_hosts is string and not equivalent to $host;

At last, if $real_allowed_hosts is not undef, then run
nova::db::mysql::host_access
