> ConnectionState.checkTimeouts resets the connection if the session timeout has expired,
whether or not we ever had a session. If one has a large, shooty cluster with a short session
timeout and a long connection timeout, this might reset the host list pointer to zero every
sessionTimeoutMs, never letting it connect to a valid, available host towards the end of the
list. On the other hand, if it is an assertion that sessionTimeout > connectionTimeout
always, then the min() call is not required and the ifelse should read "else if (elapsed >
connectionTimeoutMs)" instead of just "else".
