add the ability to disable shared folders

Add ability to disabled shared folders.

If vmware tools is not installed, you get errors and the drive is not mounted. Not all VMs will have vmware tools installed. Also, without shared folders, VMs might start faster.

To be honest, a VM without VMWare Tools is quite painful. I do think that the default should be support shared folders and warn if it can't be done.

Does the VM fail to boot for you?

I do think that shared folders are really fragile and I do think that there are better solutions out there.

Turns out that there was an issue with the box. I think it was Arch or Alpine or something like that.

@mkinney did the box boot though? I'm okay with a few error messages popping up as long as the box ends up being available.
