murano-apps repository structure is missing versions

[Serg Melikyan]

Flat structure of our murano-apps repository blocks us from publishing several versions of the same applications and don't have distinction example applications from ready-to-use applications. I propose to change structure of murano-apps repository to the corresponding to the following example:

murano-apps:
- Applications:
    - Tomcat
        - v.1.0.0 <---- optional
          - package
              - Classes
              - manifest.yaml
          - readme.md <---- optional
          - elements <---- optional
        - v.2.0.0
            - package
            - elements
            - readme.md
    - HTTPd
        - package
        - elements
        - readme.md

- Docker
    - Docker Interfaces Library
    - Standalone Host
    - Applications
        - Tomcat
        - HTTPd
        - ...
- Kubernetes:
    - Kubernetes Entities
    - Cluster
    - Pod
    - ...
- Examples:
    - TestApp1
    - TestApp2
    - ...
- readme.rst
