The version of Redis installed by the current elements uses a ppa that is stalled at 3.0.7. This seems to have some issues that are fixed in later versions. The recommended method of installing Redis is to compile the code yourself, so the elements have been changed to do this. The version was bumped to 3.2.6 (latest stable) however the Redis cluster tests were not reenabled as there still seems to be an issue with them. New config options were added to the template; these may need to be updated to make sure all the new ones are there. Change-Id: I1a604b15ade815cdb51c5484d4285e504508a6c4 Partial-Bug: 1652964
