[Improvement] Make fileset configurations transparents to underlying storage type for GVFS

### What would you like to be improved?

Currently, when we use the GVFS Java/Python client, we need to specify the storage configuration and pass them to the GVFS. for instance, assuming the underlying storage for the gvfs path 'gvfs://fileset/xxx/xxx/xxx' is a s3 path, we need to provide s3-endpoint and AKSK, which is not so elegant now as GVFS is designed to mask the detailed implementation of fileset implementation, we should not pass storage-specific configuration to GVFS.

### How should we improve?
