[CSI] disabling diagnostics in Visual Studio

[Mikhail Nesterenko]

CSI students,

By default, Visual Studio 2017 comes with Debugging and Performance
diagnostics enabled which clutters debugging window. To disable it, go
to Tools --> Options --> Debugging --> General and uncheck "Enable
Diagnostics Tools" and "Show elapsed time PerfTip while debugging".

Thanks,
