DLF (Data Lake Formation) as the REST catalog service. You need to configure 
the DLF-related properties eg: `{

+  "provider": "lakehouse-paimon",
+  "properties": {
+    "catalog-backend": "rest",

+    "warehouse": "gravitino",
+    "token-provider": "dlf",
+    "dlf-access-key-id": "xxx",
+    "dlf-access-key-secret": "xxx"
+  }
