Add DMaaP simulator for CSIT testing

A rudimentary DMaaP simulator that simply holds requests and responds
to all readers with whatever message comes in on a topic. The simulator
is placed in policy models for now but should be submitted to DMaaP.

The simulator is now working but is still extremely rough.
