Add docker file for all simulators

Some CSITs may require multiple simulators.  This adds a class that
will start all of the simulators.  A tarball is generated from which
a docker image can be built.
Added simulators for Topics: appc and appc-lcm.
Fixed licenses in files in packages directory.
Fixed per review comments:
- add version to Dockerfile
