Make `ockam tcp-outlet show` (no args) interactive by asking the user to choose from a list of tcp-outlets to show (tuify)

[nazmulidris]

Current behavior

When a user runs ockam tcp-outlet show without any arguments, currently they are shown an error message & help text. Here's a screenshot of this.

Desired behavior

Change the behavior of this command so that it becomes interactive with the user when no arguments are passed. Note that this can only be allowed to happen if:

• the terminal is interactive, and,
• the --no-input or --quiet flags have not been passed, and,
• no arguments have been passed in to the command.

This what the user flow should look like in interactive mode.

1) Use the tuify crate's select_from_list() function to ask the user to select from a list of tcp-outlet aliases, at the default node. They should be able to make multiple selections. If there are none, then simply display a message saying that none exist (not an error) and exit.

2) Once the user has made their selection(s), then run show for each selected tcp-outlets, and display the results of the show command for each tcp-outlets that they've selected.

• They should be able to make a single selection.
• If they have made no selections then exit by displaying a message to the user letting them know they did not make any selection.

The following is a video showing a generic user flow that shows the user experience when a user is asked to choose a from a list of "things". Then an action is performed on each "thing". Finally status information is reported for each action that is performed on each "thing". Please note that this flow is not specific to this issue. https://asciinema.org/a/612547

• Please use the functions select_multiple, and confirm_interactively in this file.

@Himanshu-370 We made a minor UX (user experience) update to the issue today. Instead of asking a user for confirmation once they've made their selection, we can just skip that and allow them to perform the action. Since the action is not destructive, it results in a better UX for the user.
