Service "redisCloud" not found

[XavierCastillaCarbonell]

Hi!

First of all, thanks for the example code to start on Bluemix but there is a problem there because the rediscloud declared on the manifest.yml does not longer exist and it fails to initialize.

This can bring to some confusion to rookies like me. Is it possible to be fix?

I will try to replace it for the compose for reddis service.

Edit (19/12/2016):

It was pretty easy to replace one service from another, now I got it running by connecting on the Compose for Redis instead of rediscloud.

I'll do a pull request but I'm letting the changes performed here too:
