Nicolas Peltier updated SLING-5818:
-----------------------------------
    Attachment: SLING-5818.patch

attaching patch that brings in "OutputWriter" interface, 
- PlumberServlet systematically uses it for outputing pipe execution results, with default writer outputing size & paths,
- CustomWriter can be defined by adding a "writer" subnode to the resource, properties being dubbed in the output (with instantiation of the values),
- CustomJsonWriter is a variation of CustomWriter, that comes from a JSON Object passed as a request parameter

> right now, the only way to configure the output of a pipe is to add a json as parameter of the pipe request. Sometimes the output is as important/complex as the pipe itself, and should be persisted.
> This could be also the opportunity to rewrite how writer is managed in a far from ideal if/else block. 
> servlet/plumber should *always* take a writer in account, and call it each time,
> default being path writer, writer should still be overridable through a request parameter
