Previously, we only supported intra-frequency handovers, so the
measurements where only for intra-frequency, reusing the same
measurement object. Now that we would support inter-frequency handover,
also add multiple MeasObjects for each neighbor.

Trigger F1 Handover on A3 event
...
When receiving a measurement report including an A3 event, trigger
handover towards the indicated cell.
Note that currently, we are still limited to one Cell by DU, hence
looking up a cell comes down to looking up a DU, as is done here.
