~~DRIVERS-2035~~:
Drivers must use the minimum RTT for CSOT maxTimeMS calculation instead of 90th percentile. At least 2 RTT samples are required otherwise drivers must use 0 as RTT. Only keep at most the last 10 samples. These changes were made to avoid preemptively failing operations due to inaccurate or unstable RTT measurements.
