This patch removes unwanted devref documents w.r.t. alembic migration. IMO, separate devref for sub-project is not required as it's already documented @ http://docs.openstack.org/developer/neutron/devref/alembic_migrations.html#independent-sub-project-tables Change-Id: Ida41846ff5d1be0058fd6881cceaa834c37268d7 Partial-Bug: #1560003
