    Version info handled for OSWLs

    Version info data handled for OpenStackWorkloadStats. If master node
    updated and the version info in InstallationStructure changed we have
    correct version info in OSWLs stats report.

    Fixes in collector:

    - version_info added to DB model
    - version_info added to API protocol
    - tests for version_info added

    Fixes in analytics:

    - version_info added to DB model
    - version_info fields added to CSV
    - field installation structure release info removed from CSV
    - version_info building on the fly for old OSWLs added
