[SPARK-10748][MESOS] Log error instead of crashing Spark Mesos dispatcher when a job is misconfigured

## What changes were proposed in this pull request?

Now handling the spark exception which gets thrown for invalid job configuration, marking that job as failed and continuing to launch the other drivers instead of throwing the exception.
## How was this patch tested?

I verified manually, now the misconfigured jobs move to Finished Drivers section in UI and continue to launch the other jobs.
