Connection module for Amazon IAM

.. versionadded:: 2014.7.0

:configuration: This module accepts explicit iam credentials but can also utilize
    IAM roles assigned to the instance through Instance Profiles. Dynamic
    credentials are then automatically obtained from AWS API and no further
    configuration is necessary. More Information available at:

    .. code-block:: text

        http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/iam-roles-for-amazon-ec2.html

    If IAM roles are not used you need to specify them either in a pillar or
    in the minion's config file:

    .. code-block:: yaml

        iam.keyid: GKTADJGHEIQSXMKKRBJ08H
        iam.key: askdjghsdfjkghWupUjasdflkdfklgjsdfjajkghs
        iam.region: us-east-1

    It's also possible to specify key, keyid and region via a profile, either
    as a passed in dict, or as a string to pull from pillars or minion config:

    .. code-block:: yaml

        myprofile:
            keyid: GKTADJGHEIQSXMKKRBJ08H
            key: askdjghsdfjkghWupUjasdflkdfklgjsdfjajkghs
            region: us-east-1
