 * @NM_VPN_PLUGIN_ERROR_STARTING_IN_PROGRESS: the plugin is already starting,

 * @NM_VPN_PLUGIN_ERROR_ALREADY_STARTED: the plugin is already connected, and
 *  another connect request was received
 * @NM_VPN_PLUGIN_ERROR_STOPPING_IN_PROGRESS: the plugin is already stopping,
 *  and another stop request was received
 * @NM_VPN_PLUGIN_ERROR_ALREADY_STOPPED: the plugin is already stopped, and
 *  another disconnect request was received
 * @NM_VPN_PLUGIN_ERROR_WRONG_STATE: the operation could not be performed in
 *  this state
 * @NM_VPN_PLUGIN_ERROR_BAD_ARGUMENTS: the operation could not be performed as
 *  the request contained malformed arguments, or arguments of unexpected type.
 *  Usually means that one of the VPN setting data items or secrets was not of
 *  the expected type (ie int, string, bool, etc).
 * @NM_VPN_PLUGIN_ERROR_LAUNCH_FAILED: a child process failed to launch
 * @NM_VPN_PLUGIN_ERROR_CONNECTION_INVALID: the operation could not be performed
 *  because the connection was invalid.  Usually means that the connection's
 *  VPN setting was missing some required data item or secret.
 * @NM_VPN_PLUGIN_ERROR_INTERACTIVE_NOT_SUPPORTED: the operation could not be
 *  performed as the plugin does not support interactive operations, such as
 *  ConnectInteractive() or NewSecrets()
 *
 * Returned by the VPN service plugin to indicate errors.
