Cleanup assembly process. (#565)

* Build the dependencies report at package time.

* Pull dependencies.html files from the built modules

* Add google-http-client-apache properties

* Fix apache version

* Parameterize all the properties files

* Since we are repackaging jars here, we need to include the license files as we originally were.
