Make ockam vault delete (no args) interactive by asking the user to choose from a list of vaults to delete (tuify)

[nazmulidris]

Current behavior

When a user runs ockam vault delete without any arguments, currently they shown an error & some help text. Here's a screenshot of this.

Desired behavior

Instead of showing help text, change the behavior of this command so that it becomes interactive with the user. 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 vault names. 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), display a confirmation prompt letting the user know that that a destructive operation is about to take place with the vault names they have selected. Use select_from_list() to display this prompt. 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.

3. If they choose "YES", then delete each selected vault, and display a success / failure message for each vault that got deleted.

   • If an operation succeeds then use the ✅ emoji as a prefix for the message.
   • And if it fails, then use the ⚠️ emoji as a prefix for the message.

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.

Implementation details

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

• Here's a similar PR to get some ideas from: delete node interactively #6480

• You can learn more about how to use the select_from_list() in the tuify crate here. Here is an example that is very similar to the steps you might have to take for this issue.

• Here's a file you can look at to detect when a terminal is interactive or not.

• Here's a file you can look at to see where the ockam vault delete command is implemented.
