Reconnect to DAService after binding is dead
- When the DO/PO process crashes twice with a short interval, AM gives up
and the binding will be "died". Once binding is in this state it'll never
be re-connected.
(Still, DO/PO can disable and re-enable their DAS to force DPMS to bind again
though.)
- Detect this and re-connect after one hour.
- Back-off time will be exponentially increased and never reset until DPMS
explicitly re-connects, which happens when:
-- the device rebooted,
-- the user stopped and re-started, or
-- the DAS is disabled and re-enabled.
