[HUDI-3625][RFC-60] Add StorageStrategy to HoodieStorage

[CTTY]

Change Logs

This is a part of RFC-60: Object Storage Storage Strategy https://github.com/apache/hudi/blob/master/rfc/rfc-60/rfc-60.md. The end goal is to leverage the HoodieStorage layer to further separate Hudi logic from File IO, allowing more flexibility in the physical location of files.

This PR will add StorageStrategy to HoodieStorage, but StorageStrategy will NOT be used anywhere just yet.
