More config options for Redis

[coolacid]

Currently, we only take the Redis FQDN as a configuration option. It's very likely someone might be using Redis on a non-standard port, or want a different database. Passwords are, well, a thing.

All of these things should be accessible as env variables, as they actually need to be changed in two places, one of which is NOT inside the configuration directories.

Do you want help here? Which options you want? Options

• port
• Hostname
• User
• Password
• Db instance

does I forgot any?

I think pretty much any config item available to a redis cache has. The goal here is that a lot of orgs might have an existing redis cluster they want to use with MISP. Making more configuration options makes this possible.
