[kudu-CR] [kudu-spark] Allow build against Spark 2.0 and Scala 2.11

[kudu-spark] Allow build against Spark 2.0 and Scala 2.11

This patch adds build profiles to build artifacts for Spark 2.0
and Scala 2.11. There was one tiny code change to package.scala
required to support Spark 2.0. To handle this, the different
versions of the package.scala reside in different directories and
the build profile includes the proper one. It should be a temporary
solution; a permanent one in the future would either drop support
for 1.6 or maintain separate modules compatible with 1.6 and 2.0.

The original artifactId is preserved, so the four possible
artifactIds are
- kudu-spark_2.10
- kudu-spark_2.11
- kudu-spark2_2.10
- kudu-spark2_2.11

All spark/scala combinations compile and pass the tests.
