-----------------------------------------
List of changes:
1) Added support for passing FilterQuery object instead of just Seq of keywords
2) Java had more flexible Api syntax than that of Scala so added similar Api
syntax for Scala also
3) added test cases for the all the new Api's

> Project: Spark
> Issue Type: Improvement

> The twitter stream api is very powerful provides a lot of support for
> twitter.com side filtering of status objects. When ever possible we want to
> let twitter do as much work as possible for us.
> currently the spark twitter api only allows you to configure a small sub set
> of possible filters
> String{} filters = {"tag1", tag2"}
> JavaDStream<Status> tweets =TwitterUtils.createStream(ssc, twitterAuth,
> filters);
> The current implemenation does
> private[streaming]
> class TwitterReceiver(
> twitterAuth: Authorization,
> filters: Seq[String],
> storageLevel: StorageLevel
> ) extends Receiver[Status](storageLevel) with Logging {
> . . .
> val query = new FilterQuery
> if (filters.size > 0) {
> query.track(filters.mkString(","))
> newTwitterStream.filter(query)
> } else {
> newTwitterStream.sample()
> }
> ...
> rather than construct the FilterQuery object in TwitterReceiver.onStart(). we
> should be able to pass a FilterQueryObject
> looks like an easy fix. See source code links bellow
> kind regards
