script to update Hubs list in KV store

[artlu99]

Issue: KV data store is maintained manually

Diagnosis: was fine initially, when the Hub network was more static. In times when it is dynamic (e.g., lots of staged version updates), this gets more usage and requires more manual monitoring.

The KV cannot be updated in serverless functions, because the ports are blocked due to being non-standard

Solution: a script to be run locally and scheduled, permissioned to update the KV data store
