Add remapping feature to asebamedulla

[stephanemagnenat]

It would be nice if two targets with the same id/name (for instance two Thymios) could be used together in the same network with medulla, using a mechanism similar to the identifier remapping in switch. In addition to switch, we would need to remap the node name also, as the latter is used to identify targets through the D-Bus interface. There is a forum post related to this question: https://www.thymio.org/forum/t-1179135/two-thymios-connected-to-one-pc-with-python

Now that http2 has auto-remap and has been properly re-architectured, the question is maybe whether we still need so many different switches or a single one would do?

Eventually we should converge with a single switch, but this is not urgent.
