Feature: Prompt user for credentials when connecting to smb-server the first time

[szaimen]

Describe the bug
If I want to access my smb-server the first time, I type in \\smb-server and press enter, then I don't get asked for my credentials. But if I do the same in file explorer, I get asked for the credentials and afterwards can access the server also with the files uwp app.

Requirements

• User is prompted with modal to enter password
• Modal has text feild to enter password
• Modal has connect button
• Modal has cancel button
