Autocomplete for `connect` and `delete` verbs

[mjd3]

Is your feature request related to a problem? Please describe. Whenever I want to connect to or delete an instance, I have to type the full name and sometimes it gets misspelled.

Describe the solution you'd like It would be really cool if you could autocomplete the instance name from these verbs.

Additional context Seems possible (docker does this already, ROS commands autocomplete verbs after them, etc). However, I have not looked into it much yet.
