hodec2: add penalty-time low-rxqual-ho
When bad RxQual causes handover to a cell with weaker RxLev, then
handover oscillation *will* happen, as shown in test_rxqual.ho_vty.
Introduce a penalty timer for a cell where we had bad RxQual.
This delays handover back to the cell with stronger RxLev by the penalty
timeout; hopefully the interference is gone after the timeout.
Usually, we set new configuration elements so that osmo-bsc behaves the
same as before the config item was added. In this instance, this makes
no sense, because no-one ever wants handover oscillation from bad
RxQual, which is guaranteed to happen without the new penalty timer. Set
it to 60 seconds by default, same as other penalty timers.
