Redirect to a mirror that is unreachable due to local/remote rules

[apolukhin]

For example https://mirror.mariadb.org/repo/10.6/debian/sha256sums.txt?mirrorlist&fromip=2a03:d000:3006:1f20:82e6:3199:7f4f:f485

It redirects to fastmirror.pp.ua that is unreachable from the request IP.

Could you please provide an option to fallback to another mirror or to make fromip work on any request (so that the user could override its IP address info).

Alternatively: you can mark fastmirror.pp.ua as CountryOnly: true. Or you can edit the list of ExcludedCountryCodes for this mirror.

It would be nice if this could be set via the CLI though, so it can be automated like the rest (ideas there welcome!)
