Explicitly rebind to a transport after timeout

When a TransportConnection received onServiceDisconnected() we give automatic rebinding
a chance, but if it doesn't happen within a few minutes we take matters into our hands
and attempt to rebind explicitly.
The timeout is significantly lower if the device is still unprovisioned - this is to increase
chances of proper transport binding during the setup process.

Bug: 34464359
Bug: 30964151
Test: manual, by crashing gms and gms.persistent process with "adb shell cmd activity crash #pid"
      and waiting for timeout to kick in
