Pull request overview

This PR migrates the az vm disk attach and az vm disk detach commands from hand-written SDK code to AAZ (Azure AutoRest CLI)-generated operations. The migration modernizes the codebase by leveraging automatically generated API clients while preserving the command functionality.

Changes:

  • Refactored attach_managed_data_disk to use AAZ operations (AttachDetachDataDisk for fast path, VMCreate for complex scenarios)
  • Refactored detach_managed_data_disk to use AAZ operations (VMShow and AttachDetachDataDisk)
  • Added safe_get utility function for safe nested dictionary access
