Add HorizontalPodAutoscaler (autoscaling/v2) using CPU and memory utilization
metrics to all deployment templates: app, static, gitserver, git-hook,
operator, adminrpc. Email-worker is excluded as requested.
- CPU target: 80% average utilization
- Memory target: 80% average utilization
- Each service has per-service min/max replicas in values.yaml
- Operator autoscaling defaults to disabled (enabled: false)
- Conditional via {{ if .Values.<service>.autoscaling.enabled }}
ConfigMap was removed from Helm chart (managed externally).
Secret contains all required env vars (APP_DATABASE_URL, APP_REDIS_URL,
SMTP credentials, SSH domain/key, etc.) and is always rendered
(helm.sh/resource-policy: keep prevents deletion on upgrade).
Also add APP_SSH_PORT and APP_SSH_SERVER_PRIVATE_KEY to secret template.
Replace individual configMapKeyRef env vars with envFrom + configMapRef
to inject the full ConfigMap, plus minimal env blocks for static values.
Also remove resources block from operator deployment (K8s schema validation).
