Implement Delete User From All Users Page via Delete Option

[theKunte]

This PR is for TASK 238

• The UI should be updated so we can delete a specific user on the user's webpage.

How to test it:

1. Navigate to the correct directory: - cd ui/react-ui
2. Install all packages, modules, and dependencies: - npm install
3. Start the app in the development model: - npm start

• After you start npm start you should see the following:

• Next Step:

• [ ] Navigate to /users

• Next Step:

• [ ] After all users have been loaded you should see the new Remove User with Delete Option

• Next Step:

• [ ] Select the user you want to delete [ look at the row and click on the delete field] Verify that you can see a pop-up that includes the first and lastname of the user you want to delete. The pop-up includes a Cancel and Confirm option.

• 

• When you select Cancel the pop-up closes and nothing happens. When you select Confirm you will see a pop-up on the right top that shows a confirmation if the user got deleted successfully, if not it shows an error message

• You can verify that the user no longer exists in the DB.
