Commit f0e27251 by Troy Sankey

instruct nginx to add a X-Queue-Start header

This header gets added to requests proxied by nginx to various edx apps.
The New Relic agent, if there is one, reads this header to calculate the
time each request spends between the web server (nginx) and the
application server (django or some other cms).

The specific intention of this commit is to measure the time requests
spend queued at the gunicorn layer.
