Completed testing of the new UI on the existing platforms that use
it. From testing, QNAP, Unraid, and Home Assistant (in addition to
Synology) all do not play well with using an exit node. For now,
we're disabling this setting from the UI. CLI should be updated to
also disallow selection of an exit node from these platforms.
All platforms still allow for advertising as an exit node.
