* Interestingly, it is enough to simply start a slave and then direct sessions to it. The problem seems
* to arise immediately, since simply from startup to being into SLAVE at least one internal restart happens
* and that seems sufficient to break the bolt server.
* However, that would make the test really weird, so we'll start the cluster, make sure we can connect and
* then isolate the slave, make it shutdown internally, then have it rejoin and it will switch to slave.
* At the end of this process, it must still be possible to open and execute transactions against the instance.
