[Feature Request] Confirm popup for destructive action

[roeniss]

Is your feature request related to a problem? Please describe.
Some commands like ctrl-d is not revokable but could be run by accident without any obstacle, in production cluster.

Describe the solution you'd like

• Provide CONFIRM_BEFORE_DESTRUCTIVE_ACTION option(flag).
• If this option is enabled, every descructive actions (e.g., drain, delete, kill, ...) make popup appear, and only exeucted if user move focus box and hit enter.

Describe alternatives you've considered
First time I thought that I could avoid this trouble by making this key bindings to impossible combination like ctrl-d-y-u-p-n, but AFAIK it's not possible to change default keybindings. source

Additional context

Adding some more potential solutions:

• In addition to CONFIRM_BEFORE_DESTRUCTIVE_ACTION, provide --confirm-destructive via cli args. (similar usage to --readonly)
• On destructive action, make a popup appear with a text field that requires the user to type 'delete', then move focus to OK option before hitting enter.

This extra required input should interrupt the muscle memory of ctrl-d, TAB, enter and prevent accidents. Plus, users can alias k9c="k9s --confirm-desctructive" for quick access when accessing sensitive environments like production and want an extra layer of safety.

+1 for requiring a text phrase. I almost deleted a critical app from a production cluster today when muscle memory had me pressing ctrl.
