Retrieve EC2 instance data for minions for ec2_tags and ec2_tags_list
The minion id must be the AWS instance-id or value in ``tag_match_key``. For
example set ``tag_match_key`` to ``Name`` to have the minion-id matched against
the tag 'Name'. The tag contents must be unique. The value of
``tag_match_value`` can be 'uqdn' or 'asis'. if 'uqdn', then the domain will be
stripped before comparison.
Additionally, the ``use_grain`` option can be set to ``True``. This allows the
use of an instance-id grain instead of the minion-id. Since this is a potential
security risk, the configuration can be further expanded to include a list of
minions that are trusted to only allow the alternate id of the instances to
specific hosts. There is no glob matching at this time.
.. note::
If you are using ``use_grain: True`` in the configuration for this external
pillar module, the minion must have :conf_minion:`metadata_server_grains`
enabled in the minion config file (see also :py:mod:`here
<salt.grains.metadata>`).
It is important to also note that enabling the ``use_grain`` option allows
the minion to manipulate the pillar data returned, as described above.
The optional ``tag_list_key`` indicates which keys should be added to
``ec2_tags_list`` and be split by ``tag_list_sep`` (by default ``;``). If a tag
key is included in ``tag_list_key`` it is removed from ec2_tags. If a tag does
not exist it is still included as an empty list.
..note::
As with any master configuration change, restart the salt-master daemon for
changes to take effect.

This is a very simple pillar configuration that simply retrieves the instance
data from AWS. Currently the only portion implemented are EC2 tags, which
returns a list of key/value pairs for all of the EC2 tags assigned to the
instance.
