Add limit_upstream to nginx

Server NGINX
#1

I wrote a module for nginx 4 years ago which limited the number of
connections to upstream in order that the upstream servers would not be
too
busy to work efficiently. Now I think this module is stable, and expect
it
to be merged into nginx official if possible.

the code is here:

Hi Chuanwen
Your module did not quite work for me. I opened up a ticket here.
