Currently, this isn't planned, although - since that setting is exposed
after all in the installer in the future - it would be kind of sensible
to add it to the GUI as well, I guess.
But as a separate series from this one, of course.

CC @Thomas - what do you think?

If you think this is something worth doing, I'd create a proper bugzilla
ticket with some more details.

My thinking here (roughly) would be:

* Move the {default,clamp}_zfs_arc_max() stuff to pve-common
* As for the API, probably shove it under `/nodes/{node}/config`?
  It's a per-node configuration after all, it seems to fit there best
  without introducing another endpoint just for this
* GUI-wise; if we do the above, it probably should also go under node ->
  system -> options ..
  Otherwise, add a small, separate panel for options to node -> disks ->
  zfs maybe?
