Remove pysqlite test-requirement dependency
Remove pysqlite test-requirement dependency

pysqlite is no longer needed with py27 and definitely note needed
in py34. Eliminate this as a test-requirement. This has the added
benefit of eliminating one of the very few libaries that are blocking
keystone from being python3.4 compatible.
