https://perconadev.atlassian.net/browse/PXB-3643 Problem: -------- On Azure platform, buckets with HNS (Hierarchical Namespaces) enabled, xbcloud delete operation failed. Analysis: --------- When HNS is enabled on Azure, it is no longer a flatnamespace, meanining just deleting objects as files is not sufficient. Deleting a dir before deleting all the files in directory caused delete failure. Refactor xbcloud delete to work with HNS-style directories by listing files and directories separately. Introduce a partitioned listing API with a default implementation and add Azure-specific directory detection using ResourceType. Refactor Azure listing parsing logic, and introduce a separate listin logic only for delete. With this new listing logic, xbcloud will receive information about files and directories. xbcloud will delete all files first and then delete the directories.
