The DropwizardResourceProvider endpoint does not support query.
Create a Collection Resource Provider to add query support to the JSON that is created by Dropwizard.
The 'name' of the event will need to become a attribute of a timer object, rather than a key.
_fields support is also needed also to filter which fields of the timer json are returned.
Need to decide if this end-point should only support timers, or perhaps paths are used to target the different metric types. Each metric type might need its own implementation to handle the different metric object types.
