[SPARK-2264][SQL] Fix failing CachedTableSuite

Author: Michael Armbrust <michael@databricks.com>

Closes #1201 from marmbrus/fixCacheTests and squashes the following commits:

9d87ed1 [Michael Armbrust] Use analyzer (which runs to fixed point) instead of manually removing analysis operators.
[SPARK-1112, 2156] Bootstrap to fetch the driver's Spark properties.

This is an alternative solution to #1124 . Before launching the executor backend, we first fetch driver's spark properties and use it to overwrite executor's spark properties. This should be better than #1124.

@pwendell Are there spark properties that might be different on the driver and on the executors?
