Nova server needs a name attribute

[Qiming Teng]

Currently, the only way to retrieve the 'name' attribute of a Nova server from inside a template is to {get_attr: [server, show, name] }. This is not good not only because it is inconvenient, but it implies a call to the Nova API.

An attribute needs to be added to Nova server to solve this.

tripleo would benefit greatly from this, they do many show calls to get the name:
