Integrate ceph in XCI

Openstack ansible support to deploy ceph.
The purpose of this patch is to configure the ceph,
just like we configure other openstack components.

The default is to not deploy ceph.
If you want to deploy ceph you just need to
export XCI_CEPH_ENABLED=true before running xci-deploy.sh.
When deployed successfully, the openstack storage will use ceph.
