[SPARK-11998] [SQL] When downloading Hadoop artifacts from maven, we need
to try to download the version that is used by Spark
If we need to download Hive/Hadoop artifacts, try to download a Hadoop that
matches the Hadoop used by Spark. If the Hadoop artifact cannot be resolved
(e.g. Hadoop version is a vendor specific version like 2.0.0-cdh4.1.1), we will
use Hadoop 2.4.0 (we used to hard code this version as the hadoop that we will
download from maven) and we will not share Hadoop classes.
I tested this match in my laptop with the following confs (these confs are
used by our builds). All tests are good.
```
build/sbt -Phadoop-1 -Dhadoop.version=1.2.1 -Pkinesis-asl
-Phive-thriftserver -Phive
build/sbt -Phadoop-1 -Dhadoop.version=2.0.0-mr1-cdh4.1.1 -Pkinesis-asl
-Phive-thriftserver -Phive
build/sbt -Pyarn -Phadoop-2.2 -Pkinesis-asl -Phive-thriftserver -Phive
build/sbt -Pyarn -Phadoop-2.3 -Dhadoop.version=2.3.0 -Pkinesis-asl
-Phive-thriftserver -Phive
```
