NSFS | Versioning | Delete of partial directory of nested key results in AccessDeniedError

[naveenpaul1]

Explain the changes

1. Version bucket does not support dir versioning, Deleting dir key(a/b/c/) just deletes the .folder file and does not create delete_marker.
2. If the bucket has key a/b/c/test.txt and then tries to delete key a/b/c code will throw AccessDenied error.

I want to request changes because the original issue seems incorrect to me, can you please check that throwing AccessDenied is also not thrown by AWS in the specified reproduction steps?

@romayalon added the AWS same behaviour finding in issue , For AWS aslo partial dir key is creating delete_marker for object.

@naveenpaul1 thanks for checking it,
can you run get_object before deleting the object?
my assumption is that you would receive ENOENT, because there is no such object called a/b/c.. later please check on NooBaa if this is still the behavior with the code of this PR
When deleting an object when versioning is enabled, AWS don't care if the object exists or not, they just create a delete marker.

@romayalon updated the get-object behavior in issue please check
