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' strips any domain before comparison.

The option use_grain 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.

The optional 'tag_list_key' indicates which keys should be added to 'ec2_tags_list' and be split by tag_list_sep (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: restart the salt-master for changes to take effect.

This is a very simple pillar 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.
