The changes in the koanf commit a7e867a699 introduced a regression in the startup procedure that prevented the option to disable the startup check from having an effect. This ensures the startup check is not performed if it is disabled as it was intended.
This commit replaces github.com/spf13/viper with github.com/knadh/koanf. Koanf is very similar library to viper, with less dependencies and several quality of life differences. This also allows most config options to be defined by ENV. Lastly it also enables the use of split configuration files which can be configured by setting the --config flag multiple times.
