IMPALA-14981: Add operator reconciler packaging

Add the operator reconciliation implementation and packaging assets needed
to run chart-backed Impala and optional LDAP reconciliation.

Handle LDAP disable transitions declaratively by uninstalling an existing
LDAP release when ldapEnabled is set to false.

Add ASF license headers to the new operator source and packaging files.

Testing:
- python3 -m py_compile operator/impala-operator/main.py
- kubectl config current-context (k3d-impala-live)
- kubectl apply -f operator/impala-operator/manifests/crd-impalacluster.yaml
- kubectl apply -f operator/impala-operator/manifests/rbac.yaml
- kubectl create namespace impala-14981-live
- /tmp/impala-op-venv/bin/python reconcile driver invoking _ensure_namespace, _ensure_ldap, and _ensure_impala in operator/impala-operator/main.py with spec.set persistence.accessModes[0]=ReadWriteOnce
- kubectl rollout status deployment/impala-14981-live-impala-{statestored,catalogd,impalad,hms} -n impala-14981-live
- helm -n impala-14981-live status impala-14981-live (STATUS: deployed)
- kubectl get pods -n impala-14981-live (all core pods Running/Ready)
- helm create /tmp/ldap-dummy-14981 && helm upgrade --install impala-ldap-14981-live /tmp/ldap-dummy-14981 -n impala-14981-live
- /tmp/impala-op-venv/bin/python reconcile driver invoking _ensure_ldap with ldapEnabled=false and ldapReleaseName=impala-ldap-14981-live
- helm -n impala-14981-live status impala-ldap-14981-live (fails after operator path; release removed)
