Hi [~cnauroth], Thanks for reviewing this patch.
I have incorporated your comments.
Reason for TestNativeAzureFileSystemMocked test failed was due to list api returned duplicated entries of files in a directory. I made the change to fix this issue. Now all tests are passing.
I have a new patch witt the fix. Could you grant me access to upload patch to this jira?

> Current implementation of WASB does not correctly handle multiple threads/clients calling delete on the same file. The expected behavior in such scenarios is only one of the thread should delete the file and return true, while all other threads should receive false. However in the current implementation even though only one thread deletes the file, multiple clients incorrectly get "true" as the return from delete() call..
