Get Nova Release info via Restful

[Henry]

OpenStack releases are numbered using a YYYY.N time-based scheme according to which we can know the version of Openstack. E.g. Ice house, Kilo etc.

And we have command to get the release number:
[root@crdc-c210-223 ~]# nova-manage --version
2014.1.4

Sometimes customer may want to know the version of remote openstack and check APIs accordingly. We want to provide this kind of restful api to tell them the release version.

@Henry (zhiqzhao):

As you already noted, this is a feature request. Feature requests for
nova are done with blueprints [1] (you've already done this) and with
specs [2]. I'll recommend to read [3] if not yet done. To focus here
on bugs which are a failures/errors/faults I close this one as "Invalid".
The effort to implement the requested feature is then driven only by
the blueprint (and spec).

If there are any questions left, feel free to contact me (markus_z)
in the IRC channel #openstack-nova
