> When using the yaml DSL to look up values on other entities, it would be useful to be
able to make this more dynamic by getting the entity id from the DSL (e.g. from another attribute).
> For example, a slightly simplified example below - note the DSL for "url", to retrieve
the URL from an entity whose id is set dynamically on the {{TestHttpCall}} entity:
> {noformat}
> services:
> - type: org.apache.brooklyn.entity.nosql.riak.RiakCluster
>   id: target-app
> ...
> - type: loop-test-case
>   name: "Value replicated on all Riak nodes"
>   brooklyn.config:
>     target: $brooklyn:component("target-app")
>     testSpec:
>       $brooklyn:entitySpec:
>         type: test-http-status-200
>         brooklyn.config:
>           url: $brooklyn:entity(config("targetId")).attributeWhenReady("main.uri")
> {noformat}
