[Observium] Geographically distributed pollers with poller-wrapper.py

Hi, I'm reading the following as a comment in poller-wrapper.py :

Additionally, if a hostname wildcard is passed, add it to the where clause.  This is
important in cases where you have pollers distributed geographically and want to limit
pollers to polling hosts matching their geographic naming scheme.

Do you have some advice on how I could implement this (that is, multiple pollers on multiple servers) ? Even if it is not shiny enough to be put in production, that's just for testing purposes.

I hope my brain cured since last time I posted on this ML, and is now compatible with Adam's one.
