[rdo-list] [CI] [TripleO] rdo-promote-upload-master job times out

Hi all, Just a quick FYI, the rdo-promote-upload-master job is now timing out. It looks like the 15-minute timeout is not enough now that we are uploading the images to images.rdoproject.org I've proposed https://review.gerrithub.io/290587. Please give it a deep look, I'm not too familiar with jjb and may have made a dumb mistake. Thanks, Javier
