[Wikitech-l] Changes to SWAT deployment policies, effective Monday April 30th

Hello, I have made two changes to SWAT policies today. First, we now disallow multi-sync patch deployments. See T187761[0]. This means that the sync order of files is determined by git commit parent relationships (or Gerrit's "depends-on"). This is to prevent SWAT deployers from accidentally syncing two patches in the wrong order. Second, we are reducing the number of allowed patches from 8 to 4. This is to reduce stress on the SWAT deployer as well as set expectations for requesters on the pace of the windows. See the approximate best case time spent breakdown[1] for how we came to this number. I've updated the on-wiki documentation on wikitech[2][3].
