gearpump-0.2

Highlights:

Published a tech paper about the design on https://typesafe.com/blog/gearpump-real-time-streaming-engine-using-akka
UT coverage rate to 70%
Add support for general replay-able data source to support at least once delivery.
More robust streaming. Be resilient to message loss, message duplication, and zombie processes.
Refactor Kafka data source for at least once delivery.
Support general applications besides streaming, add an experimental distrubtedshell application under experiments/.
Re-defined the AppMaster, and Task interface, It is much easier to write an application now.
Support submitting and distributing large applications jars.
Add CI tool, nightly build, code coverage, and defined a formal commit guideline.
