1. BC change in APIv2.

Farm role creation without explicitly specified FarmRole.scaling.enabled = true won't have auto-scaling enabled by default. If you want Scalr to launch instances automatically, you need to explicetly pass FarmRole.scaling.enabled = true to the API call or specify it in Farm Template.
