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

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

this should help to get insights about how the caches are filled locally

Root cause: mime types might contain charset information
Solution: be more relaxed about anything following the actual mime type

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

Change the prefix to reflect the "new" name of the service. May be this even should be configurable at some point.

This is a breaking change.

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

Fixes OXUIB-1528

Solution: Only use the hash of the version

Root cause: Version has was updated before file cache
Solution: Keep all updates in one place and switch to new version at the same time
