      Respond to recent Max Staleness Spec changes:

      • Rename maxStalenessMS to maxStalenessSeconds in ReadPreferenceSetting::fromBSON
      • Parse maxStalenessSeconds as any numeric type, storing the parsed value in Milliseconds precision.
      • The smallest value is now heartbeatFrequencyMS + idleWritePeriodMS Deferred to SERVER-26980, the current minimum value in mongos is higher than this, anyhow.
      • Implement Max Staleness prose tests for mongos in src/mongo/client/read_preference_client_test.cpp.
