shill: add support for allowing remote dbus service to claim/release devices
Add method ClaimInterface and ReleaseInterface to DBus interface
org.chromium.flimflam.Manager to allow remote DBus service to claim
the ownership of network interfaces from shill.
To reduce complexity, this service will only support one DBus service at a
time, which means disallow a DBus service from claiming interface from shill
if another DBus service currently had ownership to one or more interfaces
from shill.
When an interface is claimed by a remote DBus service, shill will stop any
activities on that interface, deregister it from the manager if it is
registered, and put it in the blacklist to avoid any further usage. Once the
interface is released by the remote DBus service, it will be removed from the
blacklist and a new device will be created/registered when it is detected
through RTNL.
BUG=chromium:435704
TEST=unittests, manual test will be done using apmanager.
