Redis Connections settings are not configurable via environment variables

[oddurmagg]

When deploying centrifugo as a docker container, it is preferable to be able to define which redis server to connect to via an environment variable.

By binding the redis_host to an environment variable in main.go this would be possible.

viper.BindEnv("redis_host")

There seems to be a workaround in #21

Hello @oddurmagg , does that workaround work fine for your case? If having environment variable is more convenient for you - I can add it in next release.

It makes me have to jump through hoops in the dockerfile where I need to pass the environment variable to the command line. And the docker CMD does not do enviroment variable expansion by default, so I need to invoke sh and through that invoke the actual binary.

see: https://docs.docker.com/engine/reference/builder/#cmd

Reading it in like all the other environment variables is much cleaner and I would prefer that.

Ok! Added in 9c3942b. I am planning to finish #73 and then make new release - hopefully during this week.

[oddurmagg]

Awesome ! Thanks

@oddurmagg unfortunately still can not release new version, because I want to include 2 pull requests into new version: #83 and #84

Finally released!
