    Checks for the version of various required boto libs in one central location. Most
    boto states and modules rely on a single version of the boto, boto3, or botocore libs.
    However, some require newer versions of any of these dependencies. This function allows
    the module to pass in a version to override the default minimum required version.

    This function is useful in centralizing checks for ``__virtual__()`` functions in the
    various, and many, boto modules and states.

    boto_ver
        The minimum required version of the boto library. Defaults to ``2.0.0``.

    boto3_ver
        The minimum required version of the boto3 library. Defaults to ``1.2.6``.

    botocore_ver
        The minimum required version of the botocore library. Defaults to ``1.3.23``.

    check_boto
        Boolean defining whether or not to check for boto deps. This defaults to ``True`` as
        most boto modules/states rely on boto, but some do not.

    check_boto3
        Boolean defining whether or not to check for boto3 (and therefore botocore) deps.
        This defaults to ``True`` as most boto modules/states rely on boto3/botocore, but
        some do not.
