open-vm-tools and VMWare Shared Folders for Ubuntu guests

(NB: adapted from this Ask Ubuntu thread -- tested to work with Ubuntu 16 LTS branches and Ubuntu 17.10)

Unlike using VMWare Tools to enable Linux guest capabilities, the open-vm-tools package doesn't auto-mount shared VMWare folders. This can be frustrating in various ways, but there's an easy fix.

TL;DR

Install open-vm-tools and run:

sudo mount -t fuse.vmhgfs-fuse .host:/ /mnt/hgfs -o allow_other
