Fix 1716 - Retry on mirror list fetching

[svartkanin]

Fixes #2716 by adding a retry for http calls and provide more logging information to make debugging easier

On the phone so hard to search, but didn't we already have a except Exception to catch all errors related to mirror tests?

And if my memory servers, we also discussed adding retry would cause delays to mirror ranking? Maybe we need to curate a list of errors like the related one in the issue that are retry worthy?

Right, this change is in the generic networking function used by the mirror list. Maybe it's better to attempt the retry on the consumer based on certain errors

@Torxed I have moved the retry local into the mirror logic instead and if that fails it should fallback now to the local mirror list
