Title: Add graceful_term_signal configuration value.

Gunicorn performs a clean shutdown on SIGQUIT, and a hard shutdown on
SIGTERM. However, Heroku uses SIGTERM to request a clean shutdown, not
SIGQUIT. (Hard shutdown is SIGKILL.) This setting allows using those
semantics, when running in a Heroku instance.
