Update git submodules

* Update docs/submodules/dovetail from branch 'master'
  - Implemented directory within OVP portal

    - Added OVP directory to portal home page as summary view to
    showcase vendors offerings that have received marks
    - Each row of table in directory summary represents a product
    offering that has received compliance verification marks and
    will be ordered by approve date
    - Currently, a vendor with multiple products will be displayed as
    separate rows, as agreed by OPNFV marketing
    - Added new angular component/controller for OVP directory secondary
    drill-down view, which provides more detailed info including
    Description, Product Info, SUT HW Version (optional from vendor)
    and SUT Version. Product info links to product_documentation field
    in Applications collection but can be improved as requirements are
    flushed out
    - Added new db fields to existing applications collection in mongodb
    - Applications collection is fetched on home page and detailed
    directory views
    - Updated Applications management view (administrator role) with
    new db fields including description, ovp_category, ovp_version,
    company_logo, approve_date, approved, sut_version, sut_hw_version,
    allowing admin to delete and add back with updates.

    - Updated participation form link for exemption process addition

    - Consider for another patch - upload form for company logos in
    Applications view for administrator to add. The initial wave of logos
    will need to be included in the patch for now when available
    from OPNFV marketing
    - Consider for another patch - improve 'Product Info' field to
    accept HTML as input allowing administrator to add raw HTML in
    mongod
    - Consider for another patch - update an existing application
    for admin role in Applications view rather than forcing a
    delete/add operation for an update
