apmanager: claim interfaces from shill
apmanager requires sole ownership of a device before it can successfully
start a hostapd on that device.
The support for reclaiming interfaces from shill when an instance of
shill is started/restarted is not in yet. It requires support for registering
DBusNameOwnerChanged callback to the dbus_object_proxy_ which is not possible
in the current generated proxy code.
BUG=chromium:435704
TEST=unittests and manual test using apmanager on stumpy router
