Objects created after S3 bucket versioning has been enabled are dropping their metadata

Here is a simple way to reproduce this:

./toggle-bucket-versioning --get --bucket test
{'Versioning': 'Suspended'}
$ openstack object create test before.dat 
$ ./toggle-bucket-versioning --on --bucket test
{'Versioning': 'Enabled'}
$ openstack object create test after.dat
$ openstack object set --property foo=bar test before.dat
$ openstack object set --property foo=bar test after.dat
$ openstack object show -f shell test before.dat
account="v1" 
container="test" 
content_length="507904" 
content_type="binary/octet-stream" 
etag="03e8a398f343ade4e1e1d7c81a66e400" 
last_modified="Wed, 05 Dec 2018 16:15:43 GMT" 
object="before.dat" 
properties="Foo='bar'" 
$ openstack object show -f shell test after.dat
account="v1" 
container="test" 
content_length="507904" 
content_type="binary/octet-stream" 
etag="03e8a398f343ade4e1e1d7c81a66e400" 
last_modified="Wed, 05 Dec 2018 16:15:08 GMT" 
object="after.dat" 

The expectation is for object metadata to work regardless of the bucket versioning status.

For people affected by this a work around this:

1. Disable bucket versioning
2. Re-created objects created while bucket versioning was created
3. Now metadata works again

And here is a snippet to easily turn on/off S3 versioning on a given
bucket: https://gist.github.com/Miouge1/b8ae19b71411655154e74e609b61f24e

I have tested this in v12.2.8. Happy to provide more info if it helps.
