Charm of juju for Virtual-Storage-Manager(VSM) Controller.

• VSM consists of vsm-controller and vsm-agent nodes.
• The charm aims to deploy the vsm-controller with vsm-api, vsm-scheduler and vsm-conductor.

• Don't support to change the config now.
• The charm-keystone is developed by openstack. So the valid service don't include the 'vsm'. So after you install the charm-keystone, you should change the code of it.
• You should run "juju ssh keystone/*", then "sudo vim /var/lib/juju/agents/unit-keystone-*/charm/hooks/keystone_utils.py".
• Of the keystone_utils.py, you should add as followed:

valid_services = {
    "vsm": {
        "type": "vsm",
        "desc": "VSM Service"
    },
    ...
}
