The mongo shell currently bases its decision on whether it should retry a command or not on the command request having a "txnNumber" argument. Since the "find" and "getMore" command requests inside of a read-only or read/write transaction will also contain a "txnNumber" argument, we'll need to set a more explicit state on the mongo shell's session to indicate that the request it is about to perform should be retried.

let numRetries =
    (cmdObj.hasOwnProperty("txnNumber") && !jsTest.options().skipRetryOnNetworkError)
    ? 1
    : 0;
