Fix for issue 3442

@terhorstd Ping!

Recording more detailed memory consumption metrics

@JanVogelsang In connection with PyNEST-NG, I have implemented memory measurement at the C++ level, see https://github.com/heplesser/nest-simulator/blob/125671c3999fef44fc42381a7b493a2db939aec4/nestkernel/kernel_manager.cpp#L358. I think it is better to have this at the C++ level, since we...

GetConnections not working with multiple threads in combination with detailed timers.

> Hm true. We could probably move the `omp parallel` outside of the `if ( not source.get() and not target.get() )` and do the `if ( is_source_table_cleared() )` inside the...
