ot::SupervisionListener::SetTimeout() method

Sets the supervision check timeout (in seconds). If the child does not hear from its parent within the given check timeout interval, it initiates the re-attach process (MLE Child Update Request/Response exchange with its parent). Setting the timeout to zero, disables the supervision check on the child. It is recommended to select a supervision check timeout value larger than the parent's child supervision interval plus the maximum time between the child's data poll transmissions.
