Description

When using a Persistant Spark context it can be beneficial to pass in new configuration options for new users/ GraphComputers. Currently the .getOrCreate call will always use the configuration from the initial construction. To work around this we should iterate over all of the properties passed into the graph computer and set them as local context properties on the thread we are operating on.

See
https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/SparkContext.scala#L630-L640

This would let different graph computers set different spark properties for use with things like the Spark Fair Scheduler.
