Log message is not clear when scale out/in

[Guangya Liu (Jay Lau)]

When I create two stacks with same template with autoscaling group, then when scale out/in, the log message would be as:

"HadoopSGroup" : {
      "Type" : "AWS::AutoScaling::AutoScalingGroup",
      "Properties" : {
        "AvailabilityZones" : ["nova"],
        "LaunchConfigurationName" : { "Ref" : "LaunchConfig" },
        "MinSize" : "1",
        "MaxSize" : "1"
      }
    },

    "HadoopSlaveScaleUpPolicy" : {
      "Type" : "AWS::AutoScaling::ScalingPolicy",
      "Properties" : {
        "AdjustmentType" : "ChangeInCapacity",
        "AutoScalingGroupName" : { "Ref" : "HadoopSGroup" },
        "Cooldown" : "30",
        "ScalingAdjustment" : "1"
      }
    },

2014-01-01 09:44:07.541 INFO heat.engine.resources.autoscaling [-] HadoopSlaveScaleUpPolicy Alarm, adjusting Group HadoopSGroup by 1

Though I created two stacks, but the log message for scale up is same for those two stacks, it is better that we add scaling group id in log message

    Update log message for scale out/in

    When create two stacks with same template with autoscaling group,
    then when scale out/in, the log message would be as
    (HadoopSlaveScaleUpPolicy is my scale up alarm and HadoopSGroup is
    my autoscaling group):

    HadoopSlaveScaleUpPolicy Alarm, adjusting Group HadoopSGroup by 1

    From above log message, I do not know which stack is being scaled up.

    This patch add scale group id to the log message so that we can know
    which group is being scale out/in.
