`User` New Modal

[pranavrao145]

Implement the functionality of the Create User button on the user index page to display a modal that loosely follows the given design:

Some design notes:

• The create uesr functionality is in a modal that pops up in the middle of the screen (and dims out the rest of the screen) when the create user button is clicked. User should be able to enter data in the form and submit without ever leaving the users index page.
• The above is just a loose design idea, make sure fonts/styles are consistent with the rest of the app
• Make the modal a view component, you'll need to reuse it with User Edit One Modal #120
