Add GUI option to easily disable Samba's NetBIOS support, to close port 139

Description

I recently discovered on the forum that I could set samba aux paramaters as follows to disable NetBIOS:

disable netbios = yes
smb ports = 445

If I correctly understand https://en.wikipedia.org/wiki/Server_Message_Block#Features then it seems that NetBIOS support is not needed if all computers are running Windows Vista or newer.

Disabling NetBIOS reduces the attack surface of one's FreeNAS server, because an entire port is closed.

Therefore, it would be nice to have a GUI method to disable NetBIOS to get port 139 closed. (I'd also argue it should be disabled by default.)

I don’t think this is a suggestion, I think it is a bug.

The GUI has a checkbox to enable/disable NetBIOS. If I disable it, port 139 is still open. That’s buggy behaviour in my books.

I’m still using Core, but today I learned that SCALE has (astonishingly!) removed the ability to set samba aux parameters. So now my workaround won’t even work. Users protesting this decision are told “file suggestions (via jira tickets) if there are fields that should be added to the webui and properly supported”, which is exactly what this ticket is, from 4 years ago, yet this just gets closed. It is discouraging to say the least.
