Update Vsphere Example

[EarthmanT]

Create a new vsphere blueprint:

• call it vsphere-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:
  vsphere_config:
    properties: &vsphere_config
      vsphere_username: { get_secret: vsphere_username }
     ...etc...

node_templates:
    network:
        type: cloudify.vsphere.nodes.Network
        properties:
            ...etc....
            vsphere_config: *vcloud_config

• Create new inputs file. Call the file vcloud.yaml.example. Provide comments on how to use it.
