osmo-bts not moving NM state "Enabled -> DisabledDependency" when Admin state becomes Locked
According to 3GPP TS 52.021 sec 5.3.1, Locking an NM object in op=Enabled NM state should trigger the NM object to move to state op=Disabled avail=Dependency (on top of moving from Admin=Unlocked->Locked).
This procedure should also be applied to all subobjects depending on the locked object.
- BSC->BTS UNLOCK msg triggers change "Disabled Dependency" -> "Disable Offline" at the BTS.
- BSC->BTS Opstart msg triggers change "Disable Offline" -> "Enabled".
