This is necessary for the keyserver to access our redis instance. We use rediss:// as we have encryption in transit enabled for our redis instance, meaning
we need to access the instance with tls enabled

Depends on D12690

Was able to launch two devices which connected to my self hosted keyserver and sent real-time messages to each other

Without specifying REDIS_URL, keyserver nodes would fail. Using redis:// instead of redis:// didn't allow for real-time communication.
