Digicert Pillar Certificates

This module will only return pillar data if the ``digicert`` runner module has
already been used to create certificates.

To configure this module, set ``digicert`` to ``True`` in the ``ext_pillar``
section of your ``master`` configuration file:

.. code-block:: yaml

    ext_pillar:
      - digicert: True
