[FBR] Update pagure.io to 2.14.1

Good Morning Everyone, I would like to do two things: - Update pagure in prod to 2.14.1 - Change the PAGURE_AUTH configuration key from 'fas' to 'openid' since legal just cleared the requirement for the FPCA on pagure.io https://lists.fedoraproject.org/archives/list/legal%40lists.fedoraproject... For 2.14.1, while not released, the changelog is going to be: - Fix typo for walking the repo when creating a diff of a PR - Have the web-hook use the signed content and have a content-type header - Fix running the tests on jenkins via a couple of fixes to pagure-admin and skipping a couple of tests on jenkins due to the current pygit2/libgit2 situation in epel7 Thoughts on these? Thanks, Pierre
