[feature](cold-data) move cold data to object storage without losing any feature(BE) (#10280)

Browse Source 
This PR supports rowset level data upload on the BE side, so that there can be both cold data and hot data in a tablet,
and there is no necessary to prohibit loading new data to cooled tablets.

Each rowset is bound to a `FileSystem`, so that the storage layer can read and write rowsets without
perceiving the underlying filesystem.

The abstracted `RemoteFileSystem` can try local caching strategies with different granularity,
instead of caching segment files as before.

To avoid conflicts with the code in be/src/io, we temporarily put the file system related code in the be/src/io/fs directory.
In the future, `FileReader`s and `FileWriter`s should be unified.
