hostapd: add default_disabled option to the supplicant
With the default configuration we generate, the supplicant starts scanning and tries to connect to any open network when the interface is enabled.
In some cases it can be desirable to prevent the supplicant from scanning by itself. For example, if on the same radio an AP is configured and an unconfigured STA is added (to be configured with WPS), the AP might not be able to beacon until the STA stops scanning.
In such a case, the STA configuration can still be required to set specific settings (e.g. multi_ap_backhaul_sta) so it can't be set to "disabled" in uci (because that would prevent the supplicant from being run at all). The alternative is to add the "disabled" parameter to the default network block in the supplicant configuration.
This patch adds a "default_disabled" setting in UCI which, when set, adds the "disabled" parameter to the supplicant default network block.
