[SPARK-14601][DOC] Minor doc/usage changes related to removal of Spark assembly

[markgrover]

What changes were proposed in this pull request?

Removing references to assembly jar in documentation.
Adding an additional (previously undocumented) usage of spark-submit to run examples.

How was this patch tested?

Ran spark-submit usage to ensure formatting was fine. Ran examples using SparkSubmit.

Looks good though a quick search showed many more instances of "assembly jar" -- you might want to zap them all here

Thanks! I only looked through docs, but let me take a closer second look.

Ok, I have replaced the usage at a few more places.

And, for those curious, the only places that are left now are:

>grep -ri "assembly jar" *
docs/submitting-applications.md:create an assembly jar (or "uber" jar) containing your code and its dependencies. Both
docs/submitting-applications.md:have assembly plugins. When creating assembly jars, list Spark and Hadoop
python/pyspark/streaming/tests.py: ("Failed to find Spark Streaming kafka assembly jar in %s. " % kafka_assembly_dir) +
python/pyspark/streaming/tests.py: raise Exception(("Found multiple Spark Streaming Kafka assembly JARs: %s; please "
python/pyspark/streaming/tests.py: ("Failed to find Spark Streaming Flume assembly jar in %s. " % flume_assembly_dir) +
python/pyspark/streaming/tests.py: raise Exception(("Found multiple Spark Streaming Flume assembly JARs: %s; please "
python/pyspark/streaming/tests.py: raise Exception(("Found multiple Spark Streaming Kinesis ASL assembly JARs: %s; please "
python/pyspark/streaming/tests.py: ("Failed to find Spark Streaming Kinesis assembly jar in %s. "
python/run-tests.py:# Find out where the assembly jars are located.

seem legit usages because they either talk about streaming backends where assembly jars are still the norm, or how users run applications as assembly/uber jars.
