Add Ansible support for Ironic

Configuration based off upstream documentation here:
http://docs.openstack.org/developer/ironic/deploy/install-guide.html

A few notes:
-ironic-api is not configured to use mod_wsgi
-several places it's noted that discoverd is going away and needs to be
replaced with ironic-inspector - (sqlite connection should be changed
too)
-currently enabling ironic reconfigures nova compute (driver and
scheduler) as well as changes neutron network settings
-a nice enhancement would be to configure the web console

Required post-deployment configuration:

Create the flat network to launch the instances:

neutron net-create --tenant-id $TENANT_ID sharednet1 --shared \
--provider:network_type flat --provider:physical_network physnet1

neutron subnet-create sharednet1 $NETWORK_CIDR --name $SUBNET_NAME \
--ip-version=4 --gateway=$GATEWAY_IP --allocation-pool \
start=$START_IP,end=$END_IP --enable-dhcp

And then the above ID is used to set cleaning_network_uuid in the neutron
section of ironic.conf.

+Ironic in Kolla
+===============
+
+Overview
+--------
+Currently Kolla can deploy the Ironic services:
+
+- ironic-api
+- ironic-conductor
+- ironic-discoverd
+
+As well as a required PXE service, deployed as ironic-pxe.
+
+Current status
+--------------
+The Ironic implementation is "tech preview", so currently instances can only be
+deployed on baremetal. Further work will be done to allow scheduling for both
+virtualized and baremetal deployments. Most probably at that time discoverd
+will be replaced by ironic-inspector.
+
+Post-deployment configuration
+-----------------------------
+Configuration based off upstream documentation_.
+
+Again, remember that enabling Ironic reconfigures nova compute (driver and
+scheduler) as well as changes neutron network settings. Further neutron setup
+is required as outlined below.
+
+Create the flat network to launch the instances:
+::
+
+    neutron net-create --tenant-id $TENANT_ID sharednet1 --shared \
+    --provider:network_type flat --provider:physical_network physnet1
+
+    neutron subnet-create sharednet1 $NETWORK_CIDR --name $SUBNET_NAME \
+    --ip-version=4 --gateway=$GATEWAY_IP --allocation-pool \
+    start=$START_IP,end=$END_IP --enable-dhcp
+
+And then the above ID is used to set cleaning_network_uuid in the neutron
+section of ironic.conf.
