Goal:

Implement OpenStack CLI commands to support attaching and detaching Manila shared filesystems to Nova instances, exposing the functionality enabled by the recent SDK updates (specifically for virtio-fs support).

Acceptance Criteria

• Command Implementation: The following commands are implemented and functional:

• • openstack server add share <server> <share>: Attaches a Manila share to a specified server.

• • openstack server remove share <server> <share>: Detaches a Manila share from a specified server.

• • openstack server share list <server>: Lists all shares attached to a specific server.

• • openstack server share show <server> <share>: Displays details of a specific share attachment.

• Parameter Support: The attach command supports the --tag argument to allow specifying a device tag (crucial for virtio-fs mounting in the guest).

• SDK Usage: The CLI properly consumes the new create_share_attachment and related methods from openstacksdk.

• Testing: Unit tests are added to verify argument parsing and proper API calls for the new commands.

• Documentation: The command-line reference documentation is updated to include server * share commands.
