dstack apply should be in the attached mode by default for any configuration type

[peterschmidt85]

Thus should include also volumes, gateways, and fleets.

Currently, the command exits immediately, and I have to wait and check from time to time to see whether it was successful.

1. For any type of configuration, it should display a table (similar to dstack ps -w)
2. For runs, the CLI should detach after the run is finished.
3. For other configurations, the CLI should detach once provisioning is finished.

So far the "attach" mode is implemented for:

• runs
• fleets
• volumes
• gateways
