Service capability tracking issue

# OpenDAL service capability overview

There is already a very limited list of supported capabilities on each service's docs.rs documentation page, however it would be very useful to have an overview of each service's specific capabilities and how widely supported each specific capability is.

Below is a extensive but very unfished overview of the capabilities of each service. My idea is to fill in the unknowns, and add whether things are currently not yet implemented or just not supported by the service itself. Later this could perhaps be added to a page on https://opendal.apache.org/docs.

The initial overview is based on whether the property of the Capability object in the code of the service is set to `true` (√) or `false` (×).

**Legend**
|Cell|Meaning|
|-|-|
|√|Supported and implemented|
|UNSUP|Not supported by underlying service|
|WIP|Possible, and in progress|
|TODO|Possible, but not yet implemented|
|×|Not supported (any reason)|
|?|Unknown|

Start by reading the service Capability objects in the code and comparing their properties with the capability overview tables in this issue. Verify unknown entries and distinguish unsupported services from unimplemented or in-progress features, including the linked WebDAV work. Done means the overview is accurate and, if adopted, is added to the OpenDAL documentation page.
