  - Stor4nfv: Install ansible version 2.4

    Ansible 2.5 release is causing errors in the installation of
    ceph-ansible (for ceph-mon). This patch fixes the ansible
    version installed on kube_master to 2.4.3 to address the ceph
    errors.

    Also, adds these post-install tasks:
     - run 'modprobe rbd'
     - create opensds default profile
     - create csi pods.
