Passerelle process model : Add support for storing raw data

Currently a c.i.p.process.model.ResultBlock contains a collection of 
ResultItems (which are enriched key/value pairs).

In the context of remote request/response interactions, current implementations 
first parse the response (e.g. a SOAP XML or so) and transform it into a 
collection of ResultItems.

This has 2 disadvantages :
- in high-throughput systems, the DB becomes the bottle-neck due to a huge nr 
of inserts
- we don't have a formal audit-trail of the actual requests and responses

We would like to introduce a system where it can be configured to alternatively 
store the raw data as sent/received, and do the parsing on-demand when needed 
(in memory).
