Modify startup parameters of ceilometer-api in devstack script
Modify startup parameters of ceilometer-api in devstack script

Since the ceilometer-api binary was generated by pbr, its startup
parameters are different from previous. The difference must be
applied to devstack plugin script or ceilometer-api can’t start
after devstack has run if the "enable_httpd_mod_wsgi_services" is
set to false in local.conf.
