273ea36 [Cheng Lian] Ignores _temporary directories

In `DataSourceStrategy.createPhysicalRDD`, we use the relation schema as the target schema for converting incoming rows into Catalyst rows.  However, we should be using the output schema instead, since our scan might return a subset of the relation's columns.

This patch incorporates #6414 by liancheng, which fixes an issue in `SimpleTestRelation` that prevented this bug from being caught by our old tests:

> In `SimpleTextRelation`, we specified `needsConversion` to `true`, indicating that values produced by this testing relation should be of Scala types, and need to be converted to Catalyst types when necessary. However, we also used `Cast` to convert strings to expected data types. And `Cast` always produces values of Catalyst types, thus no conversion is done at all. This PR makes `SimpleTextRelation` produce Scala values so that data conversion code paths can be properly tested.

Closes #5986.

**Reproduction.** Run a long-running job, go to the job page, expand the DAG visualization, and click into a stage. Your stage is now killed. Why? This is because the visualization code just reaches into the stage table and grabs the first link it finds. In our case, this first link happens to be the kill link instead of the one to the stage page.

**Fix.** Use proper CSS selectors to avoid ambiguity.

This is an alternative to #6407. Thanks carsonwang for catching this.

With descent coverage of feature transformers, algorithms, and model tuning support, it is time to graduate `spark.ml` from alpha. This PR changes all `AlphaComponent` annotations to either `DeveloperApi` or `Experimental`, depending on whether we expect a class/method to be used by end users (who use the pipeline API to assemble/tune their ML pipelines but not to create new pipeline components.) `UnaryTransformer` becomes a `DeveloperApi` in this PR.

When committing/aborting a write task issued in `InsertIntoHadoopFsRelation`, if an exception is thrown from `OutputWriter.close()`, the committing/aborting process will be interrupted, and leaves messy stuff behind (e.g., the `_temporary` directory created by `FileOutputCommitter`).

[SPARK-7684] [SQL] Invoking HiveContext.newTemporaryConfiguration() shouldn't create new metastore directory

The "Database does not exist" error reported in SPARK-7684 was caused by `HiveContext.newTemporaryConfiguration()`, which always creates a new temporary metastore directory and returns a metastore configuration pointing that directory. This makes `TestHive.reset()` always replaces old temporary metastore with an empty new one.

Following the discussion in http://apache-spark-developers-list.1001551.n3.nabble.com/python-converter-in-HBaseConverter-scala-spark-examples-td10001.html. I made some modification in three files in package examples:
1. HBaseConverters.scala: the new converter will converts all the records in an hbase results into a single string
2. hbase_input.py: as the value string may contain several records, we can use ast package to convert the string into dict
3. HBaseTest.scala: as the package examples use hbase 0.98.7 the original constructor HTableDescriptor is deprecated. The updation to new constructor is made
