This creates a new module `network/yarn` that depends on `network/shuffle` recently created in #3001. This PR introduces a custom Yarn auxiliary service that runs the external shuffle service. As of the changes here this shuffle service is required for using dynamic allocation with Spark. This is still WIP mainly because it doesn't handle security yet. I have tested this on a stable Yarn cluster.

YARN DIRECTORY LAYOUT
Hadoop Yarn related codes are organized in separate directories to minimize duplicated code.
-
common : Common codes that do not depending on specific version of Hadoop.
-
alpha / stable : Codes that involve specific version of Hadoop YARN API.
alpha represents 0.23 and 2.0.x stable represents 2.2 and later, until the API changes again.
alpha / stable will build together with common dir into a single jar
