Is your proposal related to a problem? ### Describe the solution you'd like

ddn connector-link update my_pg
--subgraph my_subgraph/subgraph.yaml
--env-file my_subgraph/.env.my_subgraph.local
--add-all-resources

if let's say I have 1000 models, it will populate my CLI with all those messages. In fact it should just return with a summary - X models added, Y commands added and Z relationships. If the user wants to see details they can add --verbose flag to the command
