Move all fabric8-analytics images to "fabric8-analytics" namespace

Most of the f8a images still live in bayesian/ namespace. All new images are in fabric8-analytics/. We'd like to move all images to the new namespace.

Acceptance criteria

@humaton in order to get this done you have to go through every repo and check current image :-( it will be rather tedious.
