This fixes an issue where attempting to load secrets the process does not have read permissions for would cause panics as well as the bit size check of the OpenID Connect 1.0 private key can potentially panic on malformed private keys. This was caused by us returning values on errors instead of nil's.
Fixes#5138

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.
