Fix mirrors hang when /status endpoint is down (#4031)

* add explicit _fetched_remote bool

* Attempt 2

* Adds about 15 seconds time-out to fetch_data_from_url with 3 retries (4, 5, 6)
Then fallsback to fully local list

* Feedbacks: 20 -> 30
Do not return early
Add debug
Remove new flag
60 second timeout for reflector

* Clean up install logs by hiding mirror scores behind --verbose
