connman integration

 I currently use iwd with NetworkManager on a couple laptops running Arch
Linux. I also am working on an RPI project with connman/iwd managing
network interfaces. Currently, if we use the connman interface to scan with
iwd, we never get a return:
"connmanctl scan wifi" just hangs and requires a ctrlC.
This was noted on the Arch connman page:
https://wiki.archlinux.org/index.php/ConnMan#Error_/net/connman/technology/wifi:_Not_supported
On my rpi project, we are using nginx/php to set it all up and we use the
'iwd station wlan0 scan' then 'connmanctl services' to select SSIDs. I
asked on the connman list and Daniel says that connman is waiting for a 0.

Scanning is supported with iwd. connmanctl scan is probably waiting for iwd
to respond with the scanning=0 signal. If iwd doesn't send out this signal
then this will hang.

Don't know if it is a connman or an iwd 'issue', but wanted to bring it up
here to see.

This should be easy to check via dbus-monitor or the test/monitor-iwd 
script in iwd.git.

For example, here's one from my test box when I run 'iwctl station wlan0 
scan'

denkenz(a)iwd-test ~/iwd $ test/monitor-iwd
{Station} [/net/connman/iwd/0/5] Scanning = True
{Station} [/net/connman/iwd/0/5] Scanning = False

So the scanning property is emitted correctly...
