Changelog:
- introduce two separate roles for middleware deployments:
    - ui-middleware: read from redis only, listen to version updates, can easily be scaled
    - updater: split out all code that writes to redis, no need to scale > 1

- Unit and Integration tests now use "inject" instead of starting a server
  and using supertest.
- Add Coverage Reports and "test:dev" mode. This enables a mocha --watch
  like workflow using nodemon, as --watch does not work with esm modules.
- Reorganized and renamed files and functions

This endpoint can be used to dynamically generate pwa.json based on configuration
on the java middleware.

Changelog:
  - Injection of code to load stylesheets is now required to be resolved during
    the build process of ui projects.
    The plugin vite-plugin-ox-css is available.

Set cache control to no-store. The ui-middleware will then only look at the remote servers for the files and never in the local cache

Root cause: Due to a bunch of redis restarts, the bull-queues got unregistered and did not register again.
Solution: On every reconnect, readd the bull queue again.

Root cause: Express automatically redirected, fastify does not
Solution: Manually do the redirect

This commit contains a fixup for the original commit 64f2780a

Cache lookups will immediately register a promise to prevent multiple requests for the same ressource

Root cause: If multiple connections are opened at the same time after an update, the ui-middleware will do multiple requests to get initial data. That went especially worse, when e2e-tests are launched against ui-middlewares with multiple clients connecting at the same time.
Soltion: Make sure, that a node already caches stuff without a response.

Root cause: configuration was only reloaded on those nodes, that did the version update. The other nodes might not notice that.
Solution: On propagated version changes, the nodes always check for config changes

Root cause: cache keys handled differently when reading/writing
Solution: make sure keys are handled equally

Fixes OXUIB-1528
