Rename repository

[VikramTiwari]

Since Dataflow supports both Java and Python, it's misleading to name it as just DataflowTemplates and only keep Java examples in there.

I suggest that it should use the preferred nomenclature of DataflowTemplates-Java the same way google-cloud SDK does.

I can help add some templates for python. Here's a sample directory which I have been keeping some samples in: https://github.com/VikramTiwari/dataflow-samples

PS: I know, even I am guilty of not using proper nomenclature, but I am not Google :)

This repository now supports both Python and Java templates (via the v2 - Flex templates).
