feat: add Writer::abort method

[v0y4g3r]

This PR:

• adds oio::Write::abort API to allow cancellation of an on-going append writer
• for those writers do not support append, adds a Write::abort implementation that simply return Ok(())
• adds delegated implementations of oio::Write::abort for all layers
• adds oio::Write::abort implementation for S3Writer as an example

This PR does not add an equivalent API in oio::BlockingWrite, since we can always add a Drop implementation for blocking writers and delete partial objects in Drop::drop.

Hi, @v0y4g3r, is this PR ready for review? Do you want to add abort API first and then add support for different services?

Maybe I can add S3 implementation along with the Writer::abort definition in this PR so that any one who is interested in that can involve in.

I'm wondering if we can add a service test for Write::abort?

Yes, we can add abort in behavior test (by ignoring not support errors)! This is PR good to get merged. How about adding a new PR for that?
