docs: Remove/update references to Heroku (#2099)
## What

This PR removes or updates references in the docs to Heroku. Most of the code samples have been replaced with a more generic `unleash.example.com` url, while other references have been removed or updated.

Also removes old OpenAPI files that are out of date and redundant with the new generation.

## Background

Come November and Heroku will no longer offer free deployments of Unleash, so it's about time we remove that claim.

Links to the heroku instance are also outdated because we don't have that instance running anymore.

Finally, the OpenAPI files we do have there are old and static, so they don't match the current reality.

## Commits

* Meta: update ignore file to ignore autogenerated docs

I must've missed the ignore file when looking for patterns.

* docs: delete old openapi file.

This seems to have been a holdover from 2020 and is probably
hand-written. It has been superseded by the new autogenerated OpenAPI docs.

* docs: add notes for heroku changes to the frontend readme and pkg

* docs: remove old openapi article and add redirects to new openapi

* docs: fix link in overview doc: point to GitHub instead of heroku

* docs: update quickstart docs with new heroku details

* docs: remove reference to crashing heroku instance

* docs: remove references to herokuapp in  code samples

* docs: add a placeholder comment

* docs: update references for heroku updates

* docs: keep using unleash4 for enterprise

* docs: remove start:heroku script in favor of start:sandbox

* docs: remove 'deploy on heroku button'

Now that it's not free anymore (or won't be very shortly), let's
remove it.

* docs: remove extra newline

securing-unleash-v3 Securing Unleash v3

This guide is only relevant if you are using Unleash Open-Source. The Enterprise edition does already ship with a secure setup and multiple SSO options.

The Unleash API is split into two different paths: /api/client and /api/admin. This makes it easy to have different authentication strategy for the admin interface and the client-api used by the applications integrating with Unleash.

General settings

Unleash uses an encrypted cookie to maintain a user session. This allows users to be logged in across multiple instances of Unleash. To protect this cookie, Unleash will automatically generate a secure token the first time you start Unleash.

Securing the Admin API

To secure the Admin API, you have to tell Unleash that you are using a custom admin authentication and implement your authentication logic as a preHook.

const unleash = require('unleash-server');
const myCustomAdminAuth = require('./auth-hook');

unleash
  .start({
    databaseUrl: 'postgres://unleash_user:passord@localhost:5432/unleash',
    adminAuthentication: 'custom',
    preRouterHook: myCustomAdminAuth,
  })
  .then((unleash) => {
    console.log(
      `Unleash started on http://localhost:${unleash.app.get('port')}`,
    );
  });

Additionally, you can trigger the admin interface to prompt the user to sign in by configuring your middleware to return a 401 status on protected routes. The response body must contain a message and a path used to redirect the user to the proper login route.

{
  "message": "You must be logged in to use Unleash",
  "path": "/custom/login"
}

Examples of custom authentication hooks:

Securing the Client API

A common way to support client access is to use pre-shared secrets. This can be solved by having clients send a shared key in an HTTP header with every client request to the Unleash API. All official Unleash clients should support this.

In the Java client this would look like this:

UnleashConfig unleashConfig = UnleashConfig.builder()
  .appName("my-app")
  .instanceId("my-instance-1")
  .unleashAPI(unleashAPI)
  .customHttpHeader("Authorization", "12312Random")
  .build();

On the Unleash server side, you need to implement a preRouter hook which verifies that all calls to /api/client include this pre-shared key in the defined header. This could look something like this.

const unleash = require('unleash-server');
const sharedSecret = '12312Random';

unleash
  .start({
    databaseUrl: 'postgres://unleash_user:passord@localhost:5432/unleash',
    preRouterHook: (app) => {
      app.use('/api/client', (req, res, next) => {
        if (req.header('authorization') !== sharedSecret) {
          res.sendStatus(401);
        } else {
          next();
        }
      });
    },
  })
  .then((unleash) => {
    console.log(
      `Unleash started on http://localhost:${unleash.app.get('port')}`,
    );
  });
