[releng] Issue #7522: koji authentication is unreliable

[Till Maas]

till reported a new issue against the project: `releng` that you are following:
``
When trying to build, koji errors too often (IMHO) with AuthError: unable to obtain a
session

For example for 51 builds it happened 7 times and every time some builds before and
afterwards cold be submitted without a problem, so it was not a outage but happenes every
few builds. IMHO this is an indication that something is somehow broken, not sure what.
The requests that failed were to build snownews qdevelop python-oslo-vmware ptlib opal
nuvola-app-tunein nodejs-utf8

Here is some info about the tasks that were created before and afterwards to help
identifying the exact times to be able to look into the logs:
