Related question: If we allow this, can we migrate a previously started cluster with port offset to one offset zero without a complete reinstall.

Currently a portOffset is allocated based on the next free offset.
We can change this to the next free portOffset+slaveAddress pair.
However since we can pre-allocate port offsets, and currently a portOffset is only linked to a slave ID, we must forbid that you change the address of a slave after you've pre-allocated a port offset.
Not sure if that leads to new problems.

The second issue (migrating clusters from one portOffset scheme to another) would require:
- Different arangodb-starter config files
- Different arangod server config files
- Different arangod server system tables (guessing)
To me this sounds like adding a LOT of complexity for a very small edge case.

I see, migration is too complex, so we do not support it. I would be in favour of allocating the next free portOffset+slaveAddress pair.
