Add vcloud Example

[EarthmanT]

Create a new vcloud blueprint:

• call it vcloud-clearwater-blueprint.yaml
• For the clearwater application, import application-blueprint.yaml instead of including it in the blueprint. (See this example.)
• Update to use Cloudify 4.0.
• Create a DSL definitions instead of using a provider context and use get_secret, example:

dsl_definitions:
  vcloud_config:
    properties: &vcloud_config
      vcloud_username: { get_secret: vcloud_username }
      vcloud_password: { get_secret: vcloud_password }
      vcloud_url: { get_secret: vcloud_url }
     ...etc...

node_templates:
    common_network:
        type: cloudify.vcloud.nodes.Network
        properties:
            ...etc....
            vcloud_config: *vcloud_config

• Delete the old vcloud inputs.
• Create new inputs file. Call the file vcloud.yaml.example.
