[SPARK-12243][BUILD][PYTHON] PySpark tests are slow in Jenkins.
## What changes were proposed in this pull request?
In the Jenkins pull request builder, PySpark tests take around [962 seconds
](https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/52530/console)
of end-to-end time to run, despite the fact that we run four Python test
suites in parallel. According to the log, the basic reason is that the long
running test starts at the end due to FIFO queue. We first try to reduce the
test time by just starting some long running tests first with simple priority
queue.
