Ceph

1. Using Ceph-ansibles stable-4.0 to install Ceph.

Steps :
1. Install Ceph on a Debian(stretch) node and a Ubuntu(18.04).
2. Using following repos for installing Ceph on nodes and I was able to pull the v14.2.18 packages on Debian strech.

Debian node :
root@debian:/etc/apt/sources.list.d# cat debian_nautilus.list
deb http://download.ceph.com/debian-nautilus xenial main

Ubuntu node : 
root@ubuntu:~# cat /etc/apt/sources.list.d/debian_nautilus.list
deb http://download.ceph.com/debian-nautilus bionic main
root@ubuntu:~#

2. Check the installed versions of Ceph on nodes :
