Code Issues Proposed changes

Enable heat to use uwsgi with devstack

Browse Source 
This change ensures that api services deployed with apache+uwsgi
by default with devstack. User can still deploy apache+mod_wsgi
by setting WSGI_MODE=mod_wsgi in local.conf.

Using HEAT_USE_APACHE=False or HEAT_USE_MOD_WSGI=False
(for backward compatibility) would deploy the services
without apache.
