idea: Make List return the path itself

[Xuanwo]

In RFC 3243: List Prefix, we make it clear that list won't return itself.

However, this behavior does not align with either local file systems or AWS S3 services, which can confuse users. Furthermore, this behavior makes it impossible to list versions of a path expected to be supported at #2611.

So I propose to change the current behavior to always return path itself if exists.

I'd like to work on this issue and other tasks about Object Versioning from tomorrow

This issue is complex; we need to review the behavior of all services and ensure they are aligned. We can start by changing the behavior test.

is this a mistake ? list file returns itself

[Xuanwo]

It appears that our implementation does not align well with the RFC. We want list to the the path itself no matter it's file or dir.
