[PATCH] hostapd: make client isolation configurable via WebUI

["Peter Müller" <peter.mueller@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 2690 bytes --]

hostapd supports client-isolation, but this feature could
not be configured via the WebUI so far. Since it might be
desired in public wireless networks, or even private ones,
it makes sense to provide a radio button to let the user
decide on.

Fixes #11974.
