Wireless devices are subject to regulations issued by authorities. For any
given AP or router, there will most likely be no case where one wireless NIC is
located in one country and another wireless NIC in the same device is located
in another country, resulting in different regulatory domains to apply to the
same box.
Currently, wireless regulatory domains in VyOS need to be configured per-NIC:
set interfaces wireless wlan0 country-code us
This leads to several side-effects:
* When operating multiple WiFi NICs, they all can have different regulatory
domains configured which might offend legislation.
* Some NICs need additional entries to /etc/modprobe.d/cfg80211.conf to apply
regulatory domain settings, such as: "options cfg80211 ieee80211_regdom=US"
This is true for the Compex WLE600VX. This setting cannot be done
per-interface.
Migrate the first found wireless module country-code from the wireless
interface CLI to: "system wireless country-code"

Move the remaining calls to check_kmod within a standard function,
with placement determined by the needs of the config script.

This was found during smoketesting as thoase started to repeadingly fail in the last weeks
File "/usr/libexec/vyos/tests/smoke/cli/test_interfaces_wireless.py", line 534, in test_wireless_security_station_address
self.assertTrue(process_named_running('hostapd'))
AssertionError: None is not true
Digging into this revealed that this is NOT related to the smoketest coding but
to hostapd/systemd instead. With a configured WIFI interface and calling:
"sudo systemctl reload-or-restart hostapd@wlan1" multiple times in a short
period caused systemd to report:
"Jul 18 16:15:32 systemd[1]: hostapd@wlan1.service: Deactivated successfully."
According to the internal systemd logic used in our version this is explained by:
/* If there's a stop job queued before we enter the DEAD state, we shouldn't act on Restart=, in order to not
* undo what has already been enqueued. */
if (unit_stop_pending(UNIT(s)))
allow_restart = false;
if (s->result == SERVICE_SUCCESS)
s->result = f;
if (s->result == SERVICE_SUCCESS) {
unit_log_success(UNIT(s));
end_state = SERVICE_DEAD;`
Where unit_log_success() generates the log message in question.
Improve the restart login in the wireless interface script and an upgrade to
hostapd solved the issue.

Check if the wireless device/modem exists in the system and the
module `ieee802111` was loaded
In cases where we do not have wireless devices, it prevents the
unexpected traceback
```
set interfaces wireless wlan0 address 192.0.2.5/32

We will use _ as CLI level divider. The XML definition filename and also
the Python helper should match the CLI node.
Example:
set interfaces ethernet -> interfaces_ethernet.xml.in
set interfaces bond -> interfaces_bond.xml.in
set service dhcp-server -> service_dhcp-server-xml.in
