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.

OpenID connect has become a standard when it comes to authentication and
in order to fix a security concern around forwarding authentication and authorization information
it has been decided to add support for it.
This feature is in beta version and only enabled when there is a configuration for it.
Before enabling it in production, please consider that it's in beta with potential bugs and that there
are several production critical features still missing such as all OIDC related data is stored in
configuration or memory. This means you are potentially going to experience issues with HA
deployments, or when restarting a single instance specifically related to OIDC.
We are still working on adding the remaining set of features before making it GA as soon as possible.
