This PR updates spark-submit to allow submitting Python scripts (currently only with deploy-mode=client, but that's all that was supported before) and updates the PySpark code to properly find various paths, etc. One significant change is that we assume we can always find the Python files either from the Spark assembly JAR (which will happen with the Maven assembly build in make-distribution.sh) or from SPARK_HOME (which will exist in local mode even if you use sbt assembly, and should be enough for testing). This means we no longer need a weird hack to modify the environment for YARN. This patch also updates the Python worker manager to run python with -u, which means unbuffered output (send it to our logs right away instead of waiting a while after stuff was written); this should simplify debugging. In addition, it fixes https://issues.apache.org/jira/browse/SPARK-1709, setting the main class from a JAR's Main-Class attribute if not specified by the user, and fixes a few help strings and style issues in spark-submit. In the future we may want to make the `pyspark` shell use spark-submit as well, but it seems unnecessary for 1.0.

This is an assembly module for Spark project. It creates a single tar.gz file that includes all needed dependency of the project except for org.apache.hadoop.* jars that are supposed to be available from the deployed Hadoop cluster. This module is off by default. To activate it specify the profile in the command line -Pbigtop-dist If you need to build an assembly for a different version of Hadoop the hadoop-version system property needs to be set as in this example: -Dhadoop.version=2.0.6-alpha
