IMPALA-6027: Retry downloading toolchain components.

We've seen intermittent 500 errors when downloading the toolchain from
S3 over the HTTPS URLs. As a first stab, this commit retries 3 times,
with some jitter.

I also changed the threadpool introduced previously to have a limit
of 4 threads, because that's sufficient to get the speed improvement.
The 500 errors have been observed both before and after the threadpool
change.

For testing, I ran the straight-forward case directly. I introduced
a broken version string to observe that retries would happen on
any error from wget.
