filecache: Modify FileCacheLocalityManager.init to pass in Spark context

[res-life]

This is used by removing a executor form locations when the executor exits:

sc.listenerBus.addToSharedQueue(new SparkListener {

   override def onExecutorRemoved

})

We have to pass in the Spark context.
I tried to get by at the private repo.

SparkContext.getActive.get

Throws the following exception:

23/06/12 09:56:29 ERROR SparkContext: Error initializing SparkContext.
java.util.NoSuchElementException: None.get
	at scala.None$.get(Option.scala:529)
	at scala.None$.get(Option.scala:527)

Looks OK, but we may not need to pass the SparkConf explicitly since it should be trivial to access via getConf on the new SparkContext parameter.

[res-life]

Done. Removed SparkConf from parameters.
