[4.0.x] Use Mimir mirror feature (apache#11622)

Use latest Mimir 0.11.2 + mirror feature. CI is now redirected to Google US Mirror.

We identified 3 problems affected by unstable Central (fails the CI runs if any of these get 4xx/5xx):
* wrapper - fixed by using alt URL
* Mimir extension loading from Central (not solved by this PR)
* two UTs `RequestTraceTest` and `TestApiStandalone` going directly to Central (not solved by this PR)
