[atlas] Probe location obfuscation

One thing I noticed for probes at homes is sometimes linked to the source DC where the fibre/copper routers are located

For example you can find probes which in reality are located in US but are marked as CN or probes which are in reality in Wisconsin but are marked in California. Of course these are extreme cases. I guess most hosts just put a pin with probe location just somewhere around where it's locate as long it's in the same city. I don't remember, as a host of 3 probes, to get any precise recommendations how to mark probe location. Personally I just put a pin in city district where probe is locate.
