[BUG] Bottleneck on IPAPI when fetching cache servers

[freQniK]

from here:

meile-gui/src/cli/sentinel.py

Line 63 in bd99edb

resp = http.get(HTTParams.IPAPI)

Sometimes IP-API blacklists IPs or throttles connections which can cause long load times for edge cases. Suggestion is to limit the TIMEOUT appropriately like in Linux to 3 seconds and only 2 retries
