    Evaluate 'None' as None in console_attributes.

    The config.yaml file suggests None as one
    of the possible values of the directive console-access-protocol,
    this is wrongly evaluated as a string in the console_attributes
    function, which causes the charm to install the pacemaker
    resource even when is not required (console-access-protocol = None).
