Not returning sub-directories under a directory in Swift

[sbcd90]

Hello,

Openstack4j ObjectStorageService.list() does not return sub-directory names under a particular directory.

The api which fails looks like this:

objectStorageService.objects().list(containerName, ObjectListOptions.create().startsWith("hello/p1/").delimiter('/').limit(9999))

The above call returns entries correctly but does not return the sub-directory name.

Kindly help.

Thanks & regards,
Subhobrata
