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

Needs some custom k8s resources (Ingress).
