Connection module for Amazon Elasticsearch Service

.. versionadded:: 3001

:configuration: This module accepts explicit IAM credentials but can also
    utilize IAM roles assigned to the instance trough 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

        es.keyid: GKTADJGHEIQSXMKKRBJ08H
        es.key: askdjghsdfjkghWupUjasdflkdfklgjsdfjajkghs

    A region may also be specified in the configuration:

    .. code-block:: yaml

        es.region: us-east-1

    If a region is not specified, the default is 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

    All methods return a dict with:
        'result' key containing a boolean indicating success or failure,
        'error' key containing the errormessage returned by boto on error,
        'response' key containing the data of the response returned by boto on success.
