Offline VM Migration Using HTTP-Based File Server

The team discussed a proposal to enable offline VM migration using an HTTP-based file server.
The preferred approach is to use WebDAV, which provides a standard protocol and existing server implementations.
Nova itself will not host the web server and will be restricted to paths under /var/lib/nova.

 Use WebDAV as the preferred protocol.

•  Avoid introducing non-standard protocols in Nova.
•  Nova will not spawn or host the web server directly.
•  Define a URL template in configuration for the remote filesystem driver (e.g., remotefs_url = https://%(host)s:9999/path/to/dav).
•  Add DevStack support to test the feature in CI.
