adds polling on the nodes' state instead of sleeping

[emduc]

Replaces the different sleeps in the integration test by busy polling on the nodes' states; we wait that all the nodes reached a concensus on the desired state, within a given timeout. Timing out raises an error but does not stop the test, this is to get a better understanding of the error: eventually the test will stop on its own but the additional logs after the timeout are useful to understand what goes wrong.
