Review Comment:
   How about creating a separate class naming `BundleResources` to handle the bundle-date creating and deleting.  The reason is that:
   
   1. `NamespaceResources` will be null if `configurationMetadataStore != null` is false, so there is a chance to throw NPE when  call `NamespaceResources.deleteBundleDataAsync(..)` or `NamespaceResources.deleteBundleDataTenantAsync(...)`:

   2. `NamespaceResources#BUNDLE_DATA_BASE_PATH` and `ModularLoadManagerImpl#BUNDLE_DATA_PATH` are duplicated.  `BundleResources` could unify them. WDYT
