CURL Transport sometimes reports failures accessing https://twitter.com in MultipleCrlOperationsTest

[LarryOsterman]

Describe the bug Several failures have been observed in the CI pipeline running the Validate Win2019_Win32Api_curl_x86 step.

The test failure I'm seeing mostly is a failure in curl.cpp:

  if (data != expected)
  {
    throw TransportException(
        "Unexpected format in HTTP response. Expecting: " + std::to_string(expected)
        + ", but found: " + std::to_string(data) + ".");
  }

The assert is reporting that instead of the expected \13 the server is sending \34 ("). This comes from CurlSession::ReadCRLF which is expecting a \r\n sequence.
