I'd like to keep the setting of the log level across subsystems even if an environment variable is provided. I've suggested a change above.

I was unaware that GOLOG_LOG_LEVEL could be used to also specify log levels for subsystems. Thanks @willscott 👍. With that in mind, it makes sense for the GOLOG_LOG_LEVEL environment variable to override any defaults and log level flags.
