test: add integration test for storagectl and storage providers
VM-only test that exercises both shipped providers through storagectl: verifies the well-known sockets exist, lists providers/volumes/ templates, creates and acquires volumes from each template (sparse-file, allocated-file, directory, subvolume), attaches a loop device to cover the block provider, and exercises the mount.storage helper.
