task flow and network from mobile device to edge orchestrator is modified

Browse Source 
1- finding which device to offlod is decided in edge orchestrator
(EdgeOrchestrator), instead of deciding while generating task
(LoadGeneratorModel)
2- file logging option is now read from config file
3- minor modification on the network delay calculation
