Unreal Engine - Toggle "Lag" Action

UELagAction.cpp

/*
 * Call to toggle lag settings, eg via binding input actions.
 * Useful for testing client side prediction, server reconciliation, server side rewind, ...
 *
 * 1) If lag and loss settings are set, reset
 * 2) If lag setting is set, set loss setting
 * 3) Else set lag setting
