    Return information about a single milestone in a named repository.

    .. versionadded:: 2016.11.0

    number
        The number of the milestone to retrieve. If provided, this option
        will be favored over ``name``.

    name
        The name of the milestone to retrieve.

    repo_name
        The name of the repository for which to list issues. This argument is
        required, either passed via the CLI, or defined in the configured
        profile. A ``repo_name`` passed as a CLI argument will override the
        repo_name defined in the configured profile, if provided.

    profile
        The name of the profile configuration to use. Defaults to ``github``.

    output
        The amount of data returned by each issue. Defaults to ``min``. Change
        to ``full`` to see all issue output.

    CLI Example:

    .. code-block:: bash

        salt myminion github.get_milestone 72
        salt myminion github.get_milestone name=my_milestone
