feat(core): service add OpenStack Swift support

[morristai]

Description

• close: Add Openstack Swift API Support #3159

Additional Notes

• There are some tricky parts in Swift that require workarounds. I've attempted to solve them all, but I still need some help from reviewers.
• Swift doesn't support creating directories directly, as there's no such concept in Swift. Instead, I use pseudo folders (Doc), but this creates some complications when listing.
• Swift doesn't support renaming files. My current implementation involves using the copy and delete API to achieve this.
• Swift doesn't support appending to the same file. It uses DLO (Dynamic Large Object) and SLO (Static Large Object) for large object storage. For SLO, it would be challenging to support at the moment because it requires manipulating the manifest contents. So the current append operation will use DLO for that.
• The behavior test results are shown below. I suspect that some of them are related to swift.

failures:
    # some bug when append size is larger >≈ 15MiB
    behavior::test_appender_futures_copy
    behavior::test_fuzz_pr_3395_case_1
    behavior::test_blocking_appender_std_copy
    behavior::test_blocking_fuzz_appender
    behavior::test_fuzz_appender

TODO

• Add new GitHub Action e2e test workflow, using openstackswift/saio:py3. (As openstackswift/saio is broken)

Seems like there're some unrelated problems in CI

You can use S3 as a reference, it's the same.

• Swift doesn't support renaming files. My current implementation involves using the copy and delete API to achieve this.

Service should only support native operations. Please don't support rename if the service doesn't provide it.

• Swift doesn't support appending to the same file.

The same. Don't support append if services not support.

• Drop append and rename as native API doesn't support
• Merge func create_dir with create_object to align native API

(I should ask for implementation details first, spent some time flighting with append 😅)

Great, let's rock!
