XVOL-1689 : ONU stays in DISCOVERED state
VOL-1586 : Possible race condition in openolt python adapter during onu discovery

1) gets Device in response of ChildDeviceDetected.
This avoids race and also removes the need for GetChildDevice.
2)Puts the Device Id into cache to use in future requests,
especially avoid the fail when calling GetChildDevice
in onuIndication because of race.
