feat: postgres reverse geocoding (#5301)

* feat: add system metadata repository for storing key values for internal usage

* feat: add database entities for geodata

* feat: move reverse geocoding from local-reverse-geocoder to postgresql

* infra: disable synchronization for geodata_places table until typeorm supports earth column

* feat: remove cities override config as we will default all instances to cities500 now

* test: e2e tests don't clear geodata tables on reset
