Add pipeline modification test for previously-recommended pipelines
Add pipeline modification test for previously-recommended pipelines

This includes every pipeline from etc/proxy-server.conf-sample since we
switched from swauth to tempauth in 1.4.1. As much as anything, I view
this as a canary for auto-insertion changes, so we can (somewhat easily)
see where new middlewares will be placed when upgrading from old swifts.
