Subject: [PATCH] [SPARK-10570][CORE] Add version info to json api
Add a new api endpoint `/api/v1/version` to retrieve various version info. This PR only adds support for finding the current spark version, however other version info such as jvm or scala versions can easily be added.
Author: Jakob Odersky <jodersky@gmail.com>
Closes #10760 from jodersky/SPARK-10570.
