  - Merge "xci: osa: Add initial dynamic inventory from PDF/IDF files"
  - xci: osa: Add initial dynamic inventory from PDF/IDF files

    The PDF and IDF files contain all the information we need for the
    virtual XCI deployment, so we can use it to create a dynamic inventory
    and get rid of all the static ones which could easily get outdated
    as PDF and IDF files evolve over time.

    This inital version of the dynamic inventory contains a lot of
    unnecessary generated information but we do that in order to ease
    the migration from static files to the dynamic inventory. The dynamic
    inventory will be improved in the future as we consume more and more
    information from the PDF and IDF files.
