Implements #21

This reverts commit d3bc298f.

since quite some time we do not report the pod as unhealthy any longer
if redis connection is gone. So in case the connection is lost, we want it
to reconnect.

Make sure to always fetch from redis once client (re-)connected.

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

This is a breaking change.

Changelog:
- Redis is now mandatory and enabled by default
- Added Sentinel, Standalone and Cluster support
- Standalone mode with sidecar is used by default
  - If no host(s) are configured, a redis sidecar is injected into the deployment
  - No extra configuration needed
  - This is intended for development and does not scale.
- Helm values have changed, see README.md:
  - `redis.host` has been renamed to `redis.hosts` and expects a list of strings with the following pattern: <localhost:6379> (needed for sentinel and cluster modes)
  - `redis.port` has been removed, see `redis.hosts`

- 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 should fix paths for apps with app root different than /

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

root cause: When redis was not available, some files could not be saved in the local memory and therefore this error permanently occurs even though the node responded correctly.
solution: Improve robustness when redis is not available

Root cause: Circular dependency causes undefined function
Solution: As the registration of the listener can be async, just use a simple setTimeout

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
