Heat scaling group doesn't override the update_policy_schema

[Angus Salkeld]

As I have been reworking tests I have noticed that:

instance group has the update policy as
  "Resources" : {
    "JobServerGroup" : {
      "UpdatePolicy" : {
        "RollingUpdate" : {

aws scale group
    'Resources': {
    'WebServerGroup': {
      "UpdatePolicy": {

and os::Heat::scalegroup
        resources:
          my-group:
            properties:
              rolling_updates:

This is all fine and well'ish, but because the heat scalegroup inherits from the aws one it kinda allows the UpdatePolicy.
(it then gets confused with PauseTime/pause_time and doesn't actually use the UpdatePolicy in the code)

I think we just need:
    update_policy_schema = {}

    Make sure UpdatePolicy is unset for Heat scaling group

    It is defined within the properties as rolling_updates.
    This patch is to make it more obvious to users that UpdatePolicy
    is not supported.
