Authentik runs ~10 pods (3 server + 3 worker + 3 pgbouncer + outpost)
which exceeds the default tier-1-cluster quota limits. Add custom-quota
label to opt out of Kyverno-generated quotas and define a Terraform-managed
ResourceQuota with limits appropriate for authentik's workload.
Enhance ingress_factory with full_host, extra_middlewares, and
skip_default_rate_limit variables. Fix TLS hosts bug to use
effective_host. Migrate 13 services from raw kubernetes_ingress_v1
resources to centralized ingress_factory module calls, removing
manual rybbit middleware CRDs where the factory now handles them.
- Remove nginx-specific ingress variables (use_proxy_protocol, proxy_timeout, additional_configuration_snippet)
- Update ingress annotations to use Traefik middleware CRDs
- Delete nginx-ingress module (replaced by traefik)
- Add new traefik middleware.tf for shared middleware definitions
- Update service modules to work with new ingress_factory interface
