Fedora 23 omnibus removal

Remove Fedora 23

 - scalpels appears to be abandonded, remove the experimental job

 - barbican-dogtag job is non-voting and unstable.  Switch it to F24
   (as an intermin, F25 should be online soon).  Fedora is our
   super-unstable cow-catcher job, I will try to get in contact and
   see if we can switch this to CentOS.  This was added with
   I77fa548e4bc96682808d3721bc5528e091871b6a

 - move infra jobs to f24
