[Improvement] Make Gravitino filesystem support both Hadoop 2 and Hadoop3

### What would you like to be improved?

Current Gravitino virtual filesystem (filesystem-hadoop3) module only builds against Hadoop 3, doesn't have a shim layer to support multiple Hadoop versions. it is better to filesystem-hadoop3 module to support multiple Hadoop versions.

### How should we improve?

I think we can refer to several projects to build a shim layer to support multiple Hadoop versions if necessary.

Start by inspecting the filesystem-hadoop3 module and its current Hadoop 3 build and API usage. Compare the module’s version-specific dependencies and entry points with the requirements for Hadoop 2 support, then review shim-layer approaches in the referenced projects. Done means the Gravitino virtual filesystem builds and works against both Hadoop 2 and Hadoop 3.
