This adds configuration and binary support for the generic registry. The container
image now supports two registry modes:
1. **dockerregistry** (default): OpenShift-integrated registry with authentication,
quotas, mirroring, and cluster integration. Uses /config.yml configuration.
2. **distribution**: Generic distribution/distribution registry for standalone use cases
without OpenShift-specific features. Uses /etc/registry/config.yaml configuration.
The generic registry configuration is sourced from:
https://github.com/openshift/appliance/blob/master/registry/config.yml
This provides flexibility to run the same container image either as an
OpenShift-integrated registry or as a standalone generic registry depending
on which binary and configuration are used.
To use the generic registry:
podman run -e REGISTRY_CONFIGURATION_PATH=/etc/registry/config.yaml <image> /usr/bin/distribution
