Improves on the fixes for #8918

Description

It just changes the ITRetryUtil.retryUntilTrue with a ITRetryUtil.retryUntil in order to increase the amount of retries — a little change on top of #8999 —, moreover it changes the number of retries and delay between retries in the HttpUtil to deal with the sporadic 401 errors.

👍 seems fine to me, I will re-run travis a few times to see if it improves things

@clintropolis — I added another retry, can you please re-run travis, or explain me how o do it, to check if it is now better?

I can keep retries going, only committers can restart travis jobs. I've been running it over the last couple of days and so far so good; thanks for looking into this 👍
