Keystone use new section for eventlet server options

Configuration options that are only relevant when running keystone
under eventlet (rather than Apache httpd) were moved to the
[eventlet_server] and [eventlet_server_ssl] groups in the
keystone.conf file to avoid confusion. This change updates devstack
to use the new non-deprecated group for these options.
