Add integrated support for parse-service-request module

[Marak]

We should add an optional property to exported View presenter which allows for automatic parsing of incoming service request.

This parsing would be applied in the middleware based on exported presenter configuration options.

The reason we want this configurable, is that parsing the incoming request may trigger buffering, which in some streaming views might not be the right use-case.

Currently I am calling psr() method as needed per view, but this is a bit messy as it adds an additional closure to the presenter code.
