fix(uwsgi): Fix broken uWSGI config (#237)

This patch introduces the following fixes to uWSGI config which
was not set up correctly to be used publicly (not behind a router,
load balancer, proxy like nginx etc.):

 - Use `http` option for a front-proxy
 - Set protocol back to `uwsgi` due to above
 - Prevent forced socket binding to `uwsgi` due to protocol change
 above (https://git.io/fj7Lw)
 - Turn on "keep-alive" support

Should fix getsentry/sentry-cli#40.
