[SPARK-24178][PYTHON] Upgrade to Py4J 0.10.7
## What changes were proposed in this pull request?
This PR proposes to upgrade Py4J to 0.10.7.
Notable changes:
- From Py4j 0.10.7, Python's 3.6 support is officially added. See
`https://github.com/bartdag/py4j/issues/301`, which PySpark currently claims.
- There was a security issue in Py4J which is, anyone can connect to
control the JVM. It's still true but at least Py4J added a simple authorization
mechanism where probably we should take a closer look again to leverage it.
It's disabled by default and there's no behaviour change. See
`https://github.com/bartdag/py4j/issues/268`.
## How was this patch tested?
Existing tests, and Jenkins tests.
