Subject: Add nbp-ansible script to deploy opensds northbound plugins

In this patch, I created another ansible script to deploy opensds
northbound plugins. Since we plan to integrate opensds with k8s
using flexvolume, I only add flexvolume role to work on it. But
the framework is extensible for adding more roles to integrate
with k8s in other ways.
Besides, I drafted the installation doc of integrating stor4nfv
with k8s in docs directory so that Compass team can work on it
more easily.

+# nbp-ansible
+This is an installation tool for opensds northbound plugins using ansible.
+
+## Install work
+
+### Pre-config (Ubuntu 16.04)
+First download some system packages:
+```
+sudo apt-get install -y openssh-server git
+```
+Then config ```/etc/ssh/sshd_config``` file and change one line:
+```conf
+PermitRootLogin yes
+```
+Next generate ssh-token:
+```bash
+ssh-keygen -t rsa
+ssh-copy-id -i ~/.ssh/id_rsa.pub <ip_address> # IP address of the target machine of the installation
+```
+
+### Install docker
+If use a standalone cinder as backend, you also need to install docker to run cinder service. Please see the [docker installation document](https://docs.docker.com/engine/installation/linux/docker-ce/ubuntu/) for details.
+
+### Install ansible tool
+```bash
+sudo add-apt-repository ppa:ansible/ansible # This step is needed to upgrade ansible to version 2.4.2 which is required for the ceph backend.
+sudo apt-get update
+sudo apt-get install ansible
+ansible --version # Ansible version 2.4.2 or higher is required for ceph; 2.0.0.2 or higher is needed for other backends.
+```
+
+### Check if the hosts can be reached
+```bash
+sudo ansible all -m ping -i nbp.hosts
+```
+
+### Run opensds-ansible playbook to start deploy
+```bash
+sudo ansible-playbook site.yml -i nbp.hosts
+```
+
+## Uninstall work
+
+### Run nbp-ansible playbook to clean the environment
+```bash
+sudo ansible-playbook clean.yml -i nbp.hosts
+```
