Public preview: App Configuration geo replication support

Azure App Configuration now supports replicating your configuration data in the configuration store to replicas in other Azure regions. Available to standard tier subscribers, any updates or additions to key/values in the configuration store or in a replica will be automatically synchronised, using an eventual consistency model. This delivers benefits including: * Increased resiliency: Replication across regions means that your configuration data will still be accessible should a service outage affect your store or any one of the replicas. * Minimise latency: Now your applications can consume the data locally, rather than issuing cross-region requests. * Optimise request distribution: Replicas and the configuration store have unique applicable request limits, allowing you to distribute requests efficiently to avoid exhausting the request limits on either the replicas or the configuration store.
