What type of PR is this?

/kind feature

What this PR does / why we need it:

This PR implements a mechanism to download files from alternate locations if possible. The functionality is added to the download role to support a mirrors key in the downloads dict which will be used to select a viable mirror. The actual mirror to be used during the download is selected as a random choice between all valid mirrors.

Since calico is publishing their artifacts in multiple locations, this PR implements a sample mirrors configuration for calicoctl download location.

Which issue(s) this PR fixes:

Fixes #8427

Special notes for your reviewer:

Does this PR introduce a user-facing change?:

That seems good for me, just one question.

# We check a number of mirrors that may hold the file and pick a working one at random

Is it possible to see which URL doesn't work to know the URL needs to be updated?

Not with the current logic since we put the no_log flag on the download task, the error is obscured, including any parameters like the URL. I could add a second task to log the results though that also has some potential to leak credentials if they are embedded in the url.

OK.
It is fine to go with current one.
When facing a maintenance issue, we will be able to add some log to know which URLs got old.
