Update git submodules

* Update docs/submodules/pharos from branch 'master'
  - generate_config.py: Fix running without eyaml

    If eyaml is not installed or misconfigured, we should output raw
    encrypted data and throw a warn/error accordingly, instead of
    bailing out completely.

    Needed for Fuel deploys on PODs that do not use PDF encryption, e.g.
    lf-pod2.
