> `once` should support updates
> -----------------------------
>
>                 Key: ARIES-1812

>             Project: Aries
>          Issue Type: Bug
>          Components: Component DSL

> {{once}} is normally used to test the existance of a given service or 
> configuration with certain properties. When there is only one tracked 
> instance and that instance is updated, {{once}} will retract the program 
> associated to the instance and publish the instance again. This is usually 
> unnecessary and {{once}} should support update operations.
