This moves a lot of machinery for commands into a context.Context with other struct values. This allows for PreRunE's to reliably load the configuration and avoids use of global vars.
This adds experimental file filters which are not guaranteed under our stability policies. These filters take effect after reading the files and before parsing their content.
This adds an access-control command that checks the policy enforcement for a given criteria using a configuration file and refactors the configuration validation command to include all configuration sources.
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.

* [FEATURE] Config Validation
* check configuration for invalid keys on startup
* allow users to manually trigger all configuration validation on a file using a cmd
* setup all defaults in config template and run tests against it to prevent accidents
* use tests to check bad configuration values are caught
* use tests to check old configuration values are caught
* add tests for specific key errors
* resolve merge conflicts
* nolint prealloc for test
