Delete extra simulator docker images

The policy-models-simulator docker image, built from
models-sim/packages, subsumes the functionality of the other simulator
images.  Deleted the other images.

This simulator still needs some of the code from the dmaap-sim modules,
so only deleted the code from the latter that is not needed by this
simulator.

Also modified the simulator launch script to use sh instead of bash.
