* now Microsoft log (Microsoft.*) are correctly supported by Nlog

* Microsoft log are now not logged under level info if tracing is not enabled.

* remove unused prefix NLog.

* Revert "Microsoft log are now not logged under level info if tracing is not enabled."

This reverts commit 00e94204e0.

* microsoft logs in console are preserved.
Only service log is clean of microsoft logs when tracing is not enabled.

* change loglevel min to debug

* Microsoft logs can be reactivate when Enhanced logging is set to true.

* adjust min & max level of serviceMicrosoftRule

* clean Microsoft logs in all NLog targets
