Makes Features2ADAMSuite use SparkFunSuite

[fnothaft]

Spawned by comments in #557; Features2ADAMSuite was using FunSuite and Features2ADAM.run() was creating a SparkContext. This led to address bind errors. This PR changes it so that we pass our own sc to Features2ADAM, and that this sc is created by a SparkFunSuite.
