Is your feature request related to a problem?

A very common troubleshooting tool is one where a superuser can potentially login as another user to be able to see what's happening to them, troubleshoot various kinds of issues, and other customer service kinds of tasks. There's no way for someone to do this with the module currently.

Describe the solution you'd like

• Add another action button to the grid that's only available to superuser. Admins and other users should not even see it.
• The button icon should be something that conveys some sort of security/visibility like a 👁️ and/or 🔏.
• When clicked, the impersonation doesn't happen right away. Instead, a module popup appears to inform and confirm the action, with the following message:

You are about to impersonate another user account. If you confirm, the website will attempt to log you in as if they logged in themselves. You'll need to logout and log back in to restore your superuser access. If you cancel, nothing will happen.

• Below that, in another style should be the following warning:

Technical Limitation: If you're using another authentication provider other than the built-in DNN provider, this feature may or may not work, depending on the type of authentication you have installed/enabled.

Describe alternatives you've considered

Upendo DNN Prompt does this, but that's focused on a different type of end-user.
