[TASK] Add warning not to put git repos into onedrive folder / CSCLSROZ-522

[JoernBerkefeld]

run on mcdev init and mcdev upgrade

check if project folder in which one of the above commands is run is potentially a synchronized folder - that would reduce performance together with git. print Util.logger.warn() message but allow to proceed

check with uncle google if there is a way to really find out if a folder is synchronized via

• onedrive
• dropbox
• google drive
• windows desktop folder
• windows documents folder
• (no clue on Mac OS)
