deployment_swift_data property for server resources

Adds a new property, deployment_swift_data for server resources. The property is a map containing the swift container and object name to use for storing the deployment data and generating temp url's for the resource. Making this a property allows it to be created externally from Heat with known values prior to stack creation. This allows the configuration of the os-collect-config agent on deployed servers prior to starting the Heat stack creation. implements blueprint split-stack-default Change-Id: Ia07e9374a4b95bd0e74fc47fb9df4bf6ad096715

+  - A new property, deployment_swift_data is added to the OS::Nova::Server
+    and OS::Heat::DeployedServer resources. The property is used to define
+    the Swift container and object name that is used for deployment data
+    for the server. If unset, the fallback is the previous behavior where
+    these values will be automatically generated.
