[SPARK-19986][Tests]Make pyspark.streaming.tests.CheckpointTests more stable
## What changes were proposed in this pull request?
Sometimes, CheckpointTests will hang on a busy machine because the
streaming jobs are too slow and cannot catch up. I observed the scheduled delay
was keeping increasing for dozens of seconds locally.
This PR increases the batch interval from 0.5 seconds to 2 seconds to
generate less Spark jobs. It should make
`pyspark.streaming.tests.CheckpointTests` more stable.
## How was this patch tested?
Jenkins
