[SPARK-3466] Limit size of results that a driver collects for each action

Right now, operations like collect() and take() can crash the driver with an OOM if they bring back too many data.

This PR will introduce spark.driver.maxResultSize, after setting it, the driver will abort a job if its result is bigger than it.

By default, it's 1g (for backward compatibility for most the cases).

In local mode, the driver and executor share the same JVM, the default setting can not protect JVM from OOM.

[SPARK-3247][SQL] An API for adding data sources to Spark SQL

This PR introduces a new set of APIs to Spark SQL to allow other developers to add support for reading data from new sources in `org.apache.spark.sql.sources`.

New sources must implement the interface `BaseRelation`, which is responsible for describing the schema of the data.  BaseRelations have three `Scan` subclasses, which are responsible for producing an RDD containing row objects.  The [various Scan interfaces](https://github.com/marmbrus/spark/blob/foreign/sql/core/src/main/scala/org/apache/spark/sql/sources/package.scala#L50) allow for optimizations such as column pruning and filter push down, when the underlying data source can handle these operations.

By implementing a class that inherits from RelationProvider these data sources can be accessed using using pure SQL.  I've used the functionality to update the JSON support so it can now be used in this way as follows:

```sql
CREATE TEMPORARY TABLE jsonTableSQL
USING org.apache.spark.sql.json
OPTIONS (
  path '/home/michael/data.json'
)
```

Further example usage can be found in the test cases: https://github.com/marmbrus/spark/tree/foreign/sql/core/src/test/scala/org/apache/spark/sql/sources

There is also a library that uses this new API to read avro data available here:

[SPARK-4182][SQL] Fixes ColumnStats classes for boolean, binary and complex data types

`NoopColumnStats` was once used for binary, boolean and complex data types. This `ColumnStats` doesn't return properly shaped column statistics and causes caching failure if a table contains columns of the aforementioned types.

This PR adds `BooleanColumnStats`, `BinaryColumnStats` and `GenericColumnStats`, used for boolean, binary and all complex data types respectively. In addition, `NoopColumnStats` returns properly shaped column statistics containing null count and row count, but this class is now used for testing purpose only.

[SPARK-3791][SQL] Provides Spark version and Hive version in HiveThriftServer2

This PR overrides the `GetInfo` Hive Thrift API to provide correct version information. Another property `spark.sql.hive.version` is added to reveal the underlying Hive version. These are generally useful for Spark SQL ODBC driver providers. The Spark version information is extracted from the jar manifest. Also took the chance to remove the `SET -v` hack, which was a workaround for Simba ODBC driver connectivity.

TODO

- [x] Find a general way to figure out Hive (or even any dependency) version.

  This [blog post](http://blog.soebes.de/blog/2014/01/02/version-information-into-your-appas-with-maven/) suggests several methods to inspect application version. In the case of Spark, this can be tricky because the chosen method:

  1. must applies to both Maven build and SBT build

    For Maven builds, we can retrieve the version information from the META-INF/maven directory within the assembly jar. But this doesn't work for SBT builds.

  2. must not rely on the original jars of dependencies to extract specific dependency version, because Spark uses assembly jar.

    This implies we can't read Hive version from Hive jar files since standard Spark distribution doesn't include them.

  3. should play well with `SPARK_PREPEND_CLASSES` to ease local testing during development.

     `SPARK_PREPEND_CLASSES` prevents classes to be loaded from the assembly jar, thus we can't locate the jar file and read its manifest.

  Given these, maybe the only reliable method is to generate a source file containing version information at build time. pwendell Do you have any suggestions from the perspective of the build process?

**Update** Hive version is now retrieved from the newly introduced `HiveShim` object.
