TIL that Batch scripts don't have an exit-on-error option. It's pretty manual to add explicit return statement when error occurred. The older version of powershell returns 0 even if the script is terminated with an error, so there need to a mechanism to intercept the error and change the return code to 1.
Also, the PR enables Python 3.8 install script to retry when download failed.Retry might be a bit complex to put into the CI script with the while, try catch, error checking logic. The most nativeMaximumRetryCountoption can't be used because Kokoro VM's powershell is not new enough.CC @jtattermusch
