Add CLI

[tubarao312]

Create a CLI that can plug into the manager and retrieve data on active tasks, workers, etc…

Will require adding more methods to Axum app to query the database. IMO this SHOULD be part of the app because the CLI is something basic that should easily be able to connect without too much set up. It would also be nice if the CLI could plug into the app from INSIDE the container (as one would with the Redis CLI)

Look into AsynQ for inspiration
