Update git submodules

* Update docs/submodules/pharos from branch 'master'
  - Merge "config/installers: Add PDF installer adapters"
  - config/installers: Add PDF installer adapters

    Previously, PDF installer adapters resided in securedlab git repo, but
    since we want to be able to use it in both securedlab (for validation
    of new PDF files during verify jobs) and installer projects (for
    actually parsing the PDF file into usable installer inputs), we
    decided to move them to a common location, also available for regular
    users.

    This change merely replicates the current adapter files from securedlab
    git repo for the following projects:
    - apex;
    - compass4nfv;
    - daisy;
    - joid;
