Introduce processors and PortageProcessor.

A processor is initialised with a database and storage provider. It
should implement the process(request, source) method, where request is a
protobuf Submission message. process() should analyse the received
files, perform any required transformations and should usually store the
files and create appropriate database entries.

Processors are multiplexed through the 'provider' variable in the
protobuf Submission message. This allows to process/analyse various
types of logs differently.
