tyagi 2cf8aa6fad Update wsgi.py to support reload from conf on SIGHUP
These changes are taken from the glance wsgi.py from where
heat wsgi.py originated. These changes are to support reload
of the service with new configuration parameters when SIGHUP
is received.

The reload of conf will only work if the server is running
with workers. If workers is 0 then it wont reload.
