'AvailabilityZones' is required but not implemented

[huangtianhua]

1. Create a stack with a AWS::AutoScaling::AutoScalingGroup resource, which required 'AvailabilityZones'. If without it, stack create will raise a error.

2. So I specify the 'AvailabilityZones' in template, and create the stack.

3. The stack create successful, but the instance is not in the 'AvailabilityZones' I specified.

4. The property 'AvailabilityZones' defined as:
     AVAILABILITY_ZONES: properties.Schema(
            properties.Schema.LIST,
            _('Not Implemented.'),
            required=True
        ),
5. I think it's a bug, as the description if we not implemented the property, we should define the 'implemented=False' and remove the defination 'required=True', as:

   AVAILABILITY_ZONES: properties.Schema(
            properties.Schema.LIST,
            _('Not Implemented.'),
            implemented=False
        ),

Or is it a good way?

also feel confused about the definition about `AVAILABILITY_ZONES` when I'm going through the code, and I didn't know the exact meaning of it within my template.

Hope you can find the appropriate implementation!

It's required in CloudFormation. So we should probably just implement it.

@usha veepuri:
Hi，I should abandon this bug, due there is a bp of this:
https://blueprints.launchpad.net/heat/+spec/implement-autoscalinggroup-availabilityzones and you can review the patch.

Given that there is a spec and blueprint for this I am going to close this bug.
