When profiling the Join / Aggregate queries via VisualVM, I noticed lots of `SpecificMutableRow` objects created, as well as the `MutableValue`, since the `SpecificMutableRow` are mostly used in data source implementation, but the `copy` method could be called multiple times in upper modules (e.g. in Join / aggregation etc.), duplicated instances created should be avoid.

[SPARK-4553] [SPARK-5767] [SQL] Wires Parquet data source with the newly introduced write support for data source API This PR migrates the Parquet data source to the new data source write support API. Now users can also overwriting and appending to existing tables. Notice that inserting into partitioned tables is not supported yet. When Parquet data source is enabled, insertion to Hive Metastore Parquet tables is also fullfilled by the Parquet data source. This is done by the newly introduced `HiveMetastoreCatalog.ParquetConversions` rule, which is a "proper" implementation of the original hacky `HiveStrategies.ParquetConversion`. The latter is still preserved, and can be removed together with the old Parquet support in the future.

This patch fixes two difficult-to-reproduce Jenkins test failures in InputOutputMetricsSuite (SPARK-5227 and SPARK-5679). The problem was that WholeTextFileRecordReaderSuite modifies the `fs.local.block.size` Hadoop configuration and this change was affecting subsequent test suites due to Hadoop's caching of FileSystem instances (see HADOOP-8490 for more details). The fix implemented here is to disable FileSystem caching in WholeTextFileRecordReaderSuite.

This patch replaces all uses of EasyMock with Mockito. There are two motivations for this: 1. We should use a single mocking framework in our tests in order to keep things consistent. 2. EasyMock may be responsible for non-deterministic unit test failures due to its Objensis dependency (see SPARK-5626 for more details). Most of these changes are fairly mechanical translations of Mockito code to EasyMock, although I made a small change that strengthens the assertions in one test in KinesisReceiverSuite.
