Unable to create FILE catalog

[liangchen78]

After I cloned the latest repo, I found I couldn't create a catalog using FILE storage type anymore. Is the file storage type support dropped?

It's not dropped, but some new flags must be set:

      polaris.features."ALLOW_INSECURE_STORAGE_TYPES": "true"
      polaris.features."SUPPORTED_CATALOG_STORAGE_TYPES": "[\"FILE\",\"S3\",\"GCS\",\"AZURE\"]"
      polaris.readiness.ignore-severe-issues: "true"
