Location: Store the OSM POI version (for future update)

[raphodn]

Story

When a new price location is provided, we only fetch basic POI data from OSM. But this POI can be updated in the future, or even deleted. We need to have a mechanism to update these POI, or at least know which version we have in OP.

Use cases

• a shop closes and the OSM POI is deleted. We want to keep its prices and location info, but maybe display a closed label ?
• a shop closes, and another reopens in replacement. the OSM POI is updated. These 2 locations will have the same OSM id+type, but we need to differenciate them (if Aldi replaces Franprix, prices for Franprix shouldn't be move to Aldi).

Todo

• new Location.osm_version field
• fetch data from OSM API
• script to init data
• how to update the data if it changes in OSM ?? (another issue to create)
