I create several platform, (let's say four) with id 1,2,3,4! all fine for now.

I have finished with platform 1 and 3, they are destroyed and everything fine.

I create 2 new plarforms,their ids are now ... 5 and 6.

Since the id is used to compute ip and port, this breaks at some point ( seen ip => 254 :( , cannot create vm ...)

We should look for new ids into deleted ids (ie here take 1 and 3 ) before taking new ids
