Allow unauthenticated access to OIDC discovery endpoints by deploying the oidc-reviewer ClusterRoleBinding to all site and global clusters.
We do enforcement on the apache/mod_oauth2 level instead.
Without domain ID provided, it was defaulting to 'Default' rather than a 'service'.
K8s Secret data fields require base64-encoded values; stringData accepts plain text and lets the API server handle encoding.
Without this, the auth plugin switches back to requesting unscoped tokens which results in the empty service catalog and services not working.
This is following merge of https://review.opendev.org/c/openstack/openstack-helm/+/993881

This change adds a keystoneauth OIDC access-token plugin that reads the current OIDC token from a file (access_token_file) instead of requiring a static inline token. It is designed for Kubernetes workload identity, where service-account/OIDC tokens rotate frequently and are projected to disk, making inline configuration brittle. The plugin preserves normal Keystone token caching and only re-reads the file when keystoneauth reauthenticates near Keystone token expiry, so rotated Kubernetes tokens are picked up automatically without forcing reauthentication on every request.
