Bump Cassandra to 2.0.8 in Travis
Ensure proper arrays for certain REST parameters

The body-parser middleware now relies on qs@1.2 which imposes an upper
limit of 20 for array parameters. Anymore will result in that parameter
being turned into an object.

For example, `[‘a’, ‘b’, … ‘z’]` will be turned into `{‘0’: ‘a’, ‘1’: ‘b’, … ’25’: ‘z’}`.
By using `OaeUtil.toArray` these parameters will always be arrays.
Removed -3 from cqlsh in travis.yaml
