Migrated from b/73788534

Currently, when we add a new server to prod, we first add it to local server_db, then ask the sync_cloudsql_access script to get all the servers from local server_db and whitelist their IP address on the tko cloud instance. When we switch to use the cros_infra_inventory, the script needs to get all the servers from the cros_infra_inventory tool, since the local_server_db will not be updated immediately.
