Documentation Test different Reconcile scenarios of ONU Go adapter with all three workflows ATT, DT and TT.
... Test suite is dedicated for only one ONU! Run robot with bbsim-kind.yaml only!
... Not for DT/TT workflow!
... Hint: default timeout in BBSim to mimic OLT reboot is 60 seconds!
... This behaviour of BBSim can be modified by 'oltRebootDelay: 60' in BBSim section of helm chart or
... used values.yaml during 'voltha up'.

Olt Deletion After Adapter Restart

... - restart the ONU adapter preferred via "kubectl delete pod"
... - delete one OLT immediately after the restart has been initiated
... - wait until the restart of the ONU adapter and the reconcile processing are finished
... - check whether the ONUs on the remaining OLT have been properly reconciled (if avaialable)
... - check whether the ONUs at the deleted OLT have disappeared from the device list
... - KV store data of these ONUs are deleted under:
... - <kvStorePrefix>/openonu/<deviceId>
... - <kvStorePrefix>/openonu/pm-data/<deviceId>
... - check for not deleted device(s) reason is still the same before restart (if available)
