> A new API endpoind will be added which expects a bucket and a flow id with 
> two existing  (and different) version identifier. When the call is 
> successfull, the response contains a list of changed components with the 
> differences similar to the result used by Show Local Changes.
> +Notes:+
> - Having the same version for both sides of the comparison will result an 
> empty list
> - Non-existing bucket or flow ids will result error response.
> - Compared to the "show local changes" we need to prepare for bigger data 
> sets. As the main purpose of this future is to compare relatively close 
> versions when updating the flow, we can consider longer results as "non 
> useful". Because of this, the results might be limited to a size, just like 
> in case of Provenance Event listing
> - This initial effort only focuses on providing the endpoint.
