This PR migrates Parquet data source to the newly introduced `FSBasedRelation`. `FSBasedParquetRelation` is created to replace `ParquetRelation2`. Major differences are: 1. Partition discovery code has been factored out to `FSBasedRelation` 1. `AppendingParquetOutputFormat` is not used now. Instead, an anonymous subclass of `ParquetOutputFormat` is used to handle appending and writing dynamic partitions 1. When scanning partitioned tables, `FSBasedParquetRelation.buildScan` only builds an `RDD[Row]` for a single selected partition 1. `FSBasedParquetRelation` doesn't rely on Catalyst expressions for filter push down, thus it doesn't extend `CatalystScan` anymore After migrating `JSONRelation` (which extends `CatalystScan`), we can remove `CatalystScan`. <!-- Reviewable:start --> [<img src="https://reviewable.io/review_button.png" height=40 alt="Review on Reviewable"/>](https://reviewable.io/reviews/apache/spark/6090) <!-- Reviewable:end --> Author: Cheng Lian <lian@databricks.com> Closes #6090 from liancheng/parquet-migration and squashes the following commits: 6063f87 [Cheng Lian] Casts to OutputCommitter rather than FileOutputCommtter bfd1cf0 [Cheng Lian] Fixes compilation error introduced while rebasing f9ea56e [Cheng Lian] Adds ParquetRelation2 related classes to MiMa check whitelist 261d8c1 [Cheng Lian] Minor bug fix and more tests db65660 [Cheng Lian] Migrates Parquet data source to FSBasedRelation

In a REPL/notebook environment, its very easy to lose a reference to a StreamingContext by overriding the variable name. So if you happen to execute the following commands ``` val ssc = new StreamingContext(...) // cmd 1 ssc.start() // cmd 2 ... val ssc = new StreamingContext(...) // accidentally run cmd 1 again ``` The value of ssc will be overwritten. Now you can neither start the new context (as only one context can be started), nor stop the previous context (as the reference is lost). Hence its best to maintain a singleton reference to the active context, so that we never loose reference for the active context. Since this problem occurs useful in REPL environments, its best to add this as an Experimental support in the Scala API only so that it can be used in Scala REPLs and notebooks.

We make special treatment for +inf in `Bucketizer`. This could be simplified by always including the largest split value in the last bucket. E.g., (x1, x2, x3) defines buckets [x1, x2) and [x2, x3]. This shouldn't affect user code much, and there are applications that need to include the right-most value. For example, we can bucketize ratings from 0 to 10 to bad, neutral, and good with splits 0, 4, 6, 10. It may reads weird if the users need to put 0, 4, 6, 10.1 (or 11).
