Allow REDIS Password and ZMQ Switch
This code change allows for 2 new optional env variables REDIS_PASSWORD and ZMQ_ENABLE. Current deployments without these variables aren't affected.
Not sure whether redis password is correctly loaded from docker-compose. Anyway ZMQ and redis password are two different concerns, so it would make sense to split the PR.
LGTM, but we should have the env vars documented inside template.env, and picked up and forwarded to the container in the docker-compose.yml file as well.
Also misp-modules needs to pick up the password as well.
This PR would solve https://github.com/MISP/misp-docker/issues/9
Broke as is, https://github.com/MISP/misp-docker/pull/107 supersedes it
