[New-bugs-announce] [issue36939] Allow to use shutil.copytree for existing destination directory with optional argument

[jack1142]

New submission from jack1142 <kuba.kuczys at gmail.com>:

Currently shutil.copytree will allow to copy tree only if destination directory doesn't exist. I think there could be added `exist_ok` keyword argument (defaulting to `False`), which when set to `True` would prevent function from raising `FileExistsError`.
This is pretty easy to implement as `os.makedirs` command that raises this error already has `exist_ok` kwarg, which prevent function from raising that exception already.
