Title: add process arguments before spawning instruments 

e.g usage
capability[:processArguments] = "forceLogout"
in our app, we have process arguments that we can send to instruments process before starting UI automation.
e.g usage in ios Code to send in processArguments
NSArray *processArguments = [[NSProcessInfo processInfo] arguments];
