     new fdf7688  Rewrite URL before all remap plugins run
fdf7688 is described below

commit fdf76885b5cf5403cfc008c307d6a2034b248422
Author: Gancho Tenev <gancho@apache.org>
AuthorDate: Fri Feb 8 16:17:19 2019 -0800

    Rewrite URL before all remap plugins run
    
    Rewriting the url *before* running all plugins instead of *after*
    which would guarantee that:
    - all plugins would get the same TSRemapRequestInfo::reqiestUrl
      (first plugin in the chain would not be special)
    - all plugins would treat TSRemapRequestInfo::reqiestUrl the same
      way consistently as a *remapped* URL which makes the first plugin
      really not different from the rest
    - there would be a remapped URL default in case the remap rule had
      no plugins OR none of the plugins modifed the mapped URL
    
    Also turning off url_sig and cookie_remap plugin unit-tests impacted
    by this not backwards compatible change.
