Option to (selectively) share host folders with Waydroid #36
Description
Basically giving a nice graphical way to perform https://docs.waydro.id/faq/setting-up-a-shared-folder for Ubuntu Touch devices; might only make sense to implement for 20.04, so using a e.g. /etc/systemd/system/waydroid-container.service.d/shared-folders.conf (needs root to create dir & file) which adds another ExecStartPre under [Service] could work for example?
