vdev removal is in the GUI

[danb35]

I recall a few recent threads about vdev removal--it's been in Free/TrueNAS since at least 11.3, though it seems it was introduced pretty quietly, as most people don't know about it. Originally, at least, it was CLI only. But at some point by 12.0-U4, it was put into the GUI--just go into the pool's status, click the kebab menu next to the vdev you want to remove, and select "Remove".

If it still works as I understand it its worth pointing out that its not 100% free, and will result in a minor memory impact on the server, thus you shouldn't just add/remove vdevs willy-nilly because you can :)
