Keystone deploy switch

Browse Source 
Currently there's a boolean KEYSTONE_USE_MOD_WSGI to switch between
running keystone in mod_wsgi and eventlet. We've got a need to
support more/different deployment options (e.g., uwsgi), so a
boolean is inadequate.

A new input variable KEYSTONE_DEPLOY is introduced that can be
set to mod_wsgi or eventlet (and other values in future) to
control how keystone is deployed. KEYSTONE_USE_MOD_WSGI is
deprecated.
