Removed the db recipe

The db recipe have been removed. It is up to the operator to
setup the database, users, and grants before deploying openstack.
It has been moved to the `openstack-db` recipe in the
`openstack-ops-database` wrapper cookbook.  Also, remove database
from Berksfile, and pointed berksfile to metadata, like our other
cookbooks.
