Add CLOUD_REVISION or something equivalent to new ASG when on cluster page

[jperry]

Hey guys,

It would be nice if there was a free form field that was passed down to the user data template as a variable that you could use for every new ASG on the rolling cluster page. It seems there are only fields when create a new ASG on /autoScaling/create page.

Hey guys,

I don't mind adding this to only support my installation if you don't think this would be helpful for anyone. I posted something in the google groups regarding some pointers to how to add a field if someone would be able to reply quickly. https://groups.google.com/forum/#!topic/AsgardUsers/xwrjLWtyBXs

Thanks in advance.
