config WorkerConfig

hey! I found a problem.This seems to prevent me from configuring my redis server url.
In the config/config.goServerURL string `mapstructure:"serverurl"` is inconsistent config/viper_config.go pitaya.worker.redis.url
And lost "pitaya.worker.redis.password": workerConfig.Redis.Password,.
I'm not sure there's a similar problem out there.

yes, I appended 'password' and 'database'
