Introducing a in progress sentinel that gets verified before running the first time experience. If we can get a handle for this sentinel, we proceed with the first time run, otherwise, it means there is a first time experience running already, in which case we continue running dotnet normally, even though the final (real) sentinel is not present yet. This prevents multiple dotnet commands from running the first time experience in parallel and prevents us from running into parallel nuget restores.
