The installer `arc_max` option ZFS was introduced in [0], this exposes this option in the GUI/TUI installer for PVE installations.
This can be adjusted when creating a ZFS RAID under "Advanced Options". The default value is choosen as 10% of system memory, clamped to between 64 MiB as lower limit and 16 GiB as upper limit. For PBS and PMG, the option is (currently) hidden. Tested by installing PVE, PBS and PMG, using both the GUI and TUI installer. For PVE, checked that the `zfs` module option gets correctly written & applied, the latter by looking at the output of `arc_summary`. For PBS and PMG, verified that no modprobe options file is created and the ARC size is set to default.
