Fix pyspark to work on yarn mode when spark version is lower than or equal
to 1.4.x
### What is this PR for?
pyspark.zip, py4j-\*.zip should be distributed to yarn nodes to make
pyspark function but this hasn't been working after #463 because [`if
(pythonLibs.length ==
pythonLibUris.size())`](https://github.com/apache/incubator-zeppelin/blob/master/spark/src/main/java/org/apache/zeppelin/spark/SparkInterpreter.java#L329)
condition will never be true. This PR fixes this issue by changing this if
condition to be `pythonlibUris.size() == 2`, while integer 2 refers
pyspark.zip and py4j-\*.zip.
In addition, yarn-install documentation has been updated.
### What type of PR is it?
Bug Fix
### Is there a relevant Jira issue?
No. But the issue has reported via [user mailing
list](http://apache-zeppelin-users-incubating-mailing-list.75479.x6.nabble.com/Can-t-get-Pyspark-1-4-1-interpreter-to-work-on-Zeppelin-0-6-td2229.html#a2259)
