Remove openstack-ceilometer-api pre upgrade check

This change removes the pre upgrade check for a running
openstack-ceilometer-api service as this service doesn't exists in
Newton. Ceilometer API runs under httpd:
[root@overcloud-controller-0 ~]# httpd -t -D DUMP_VHOSTS | grep ceilo
10.0.0.23:8777         overcloud-controller-0.internalapi.localdomain
(/etc/httpd/conf.d/10-ceilometer_wsgi.conf:6)
