Missing buffer size option for wsgi lead to 502

[rafspiny]

When deploying a Flask app to EBS (using the tutorial) one can face 502 HTTP status code when returning response with a size bigger than 4096.

invalid request block size: 4654 (max 4096)...skip

Apparently this script does not contemplate to configure the buffer-size option for WSGI.
After reading the doc about configuration on EBS I am not sure if I can specify such an option without doing a hacky replace of the uwsgi-start.sh script and rerun it.

I'm also having this issue. A fix would be nice. :)
