Fetch the default queues value from the env

mostly so that purely env-based configurations are possible, as this is the only flag (I think?) that causes an exit when not provided.

For reference, I'm using goworker over here in a docker + ansible context where it'd be super handy to keep all of my configuration in an env dict/hash for ease of things like upstart conf templates.

Hey @meatballhat, thanks for the PR. Sorry it's taken so long to get back to you.

I'm hesitant to have some config as flags, with other configs only as environment variables. The $REDIS_URL and $REDIS_PROVIDER variables serve for compatibility with Resque and Sidekiq. For now, you can run your process as goworker -queues=$QUEUES.

However, I would be interested in a clean way to implement ENV-based configuration. Perhaps something like kelseyhightower/envconfig would make sense. What do you think?

@benmanns No worries 😺 I'd say the envconfig way seems reasonable enough. I'm guessing you're wanting to avoid this kind of repetition (?):

• set up some string defaults from the env
• doing more stuff during init
• yet more stuff after flag parse
