[issue20849] add exist_ok to shutil.copytree

[Elias Zamaria]

Elias Zamaria added the comment:

Here is a patch that adds the option.

I am not very familiar with the internals of shutil and os so I would recommend that someone else review it.

I haven't added any tests. I can try to if anyone wants but I am not sure how long it will take me or if I will find the time any time soon.
