Accela Zhao 8260169fa7 Don't create cgsnapshot if cg is empty ... If we create cgsnapshot from an empty consistencygroup, it fails with "Consistency group is empty. No cgsnapshot will be created". However, a cgsnapshot object is still created in DB. This is because in cinder/consistencygroup/api.py::_create_cgsnapshot, we create cgsnapshot object before we test whether the corresponding consistencygroup is empy. This patch fixes this problem by moving the creation of cgsnapshot object to after the test of whether consistencygroup is empty.
