separation of initialization of children from launching of the children;
children launching is started in a greenlet in on_start; initialization then
verifies the children have been launched to proceed.

Implement launch of the children agents (sub-platforms and instruments) on_start  (and terminate them on_quit) as opposed to lauching them in INITIALIZE (and terminathem in RESET). All tests OK but method not enabled because the termination of the processes is not completely clean: there are exceptions with "already dead?" messages, and also the logic is a bit more complicated: need to launch the children asynchronously  as the direct launch in on_start does not work (timeout).
