Directory object (key/) is not supported combined with versioning Enabled/Suspended

[romayalon]

Environment info

• NooBaa Version: 5.18
• Platform: All

Actual behavior

1. A .folder file that gets created by uploading a directory object is currently not being versioned when versioning is enabled, on a second PUT of the same directory object the .folder will get overridden, and on delete we won't create a delete marker for this file.
   same for MPU, delete latest/delete version id/lists/get/head etc, we need to support all flows with directory object combined with versioning.

Expected behavior

1. Content directory object can be versioned.

Steps to reproduce

Regular put example -

1. aws s3 api put-object --bucket bucket1 --key a/b/c/ --body some_file_v1.txt
2. aws s3 api put-object --bucket bucket1 --key a/b/c/ --body some_file_v2.txt
3. aws s3 api list-object-versions - result - got only the second version
