> I propose to add a new FileStore example. Below are the ideas:
> - It uses Ratis to store files so that the files are replicated in a Raft group.
> - It is not a file system -- it only supports basic operations such as read, write and delete but not ls, rename, etc.
> - Its state machine stores the file data separated from the log in order to reduce the log size.
> - It can be served as a Ratis performance test.
