Build a login form component

For our login form, we must take in an email, and a password, send that to our login API call function, and insert the token into local storage if the login was successful.

To achieve this, we import the following:

// ingress/frontend/src/components/LoginForm.tsx
import React from 'react';
import '../Login.css';
import { login } from '../api/login';
interface LoginFormProps {
    setToken: (token: string) => void;
}

With the preceding imports and interface, we can define our login form component's signature with the code below:

// ingress/frontend/src/components/LoginForm.tsx
export const LoginForm: React.FC<LoginFormProps> = (
        { setToken }
    ) => {
    const [email, setEmail] = React.useState<string>("");
    const [password, setPassword] = React.useState<string>("");
    const submitLogin = () => {
        . . .
    };
    const handlePasswordChange = (
      ...
