[RFE] Expose supported power states

[Hironori Shiina]

This RFE proposes to expose supported power states via ironic API. This work was split from the work for supporting soft shutdown and NMI injection[1].

Ironic has been supporting soft shutdown and NMI injection from Ocata. While reviewing the SPEC[2], it was proposed to expose supported power states via API and this change was approved. However, the API change was not completed. We need to discuss this API change again independently of the original RFE.

Thanks Hironori. I think the API will be fairly straightforward, and changes in API require a spec.

    Expose supported power states

    This SPEC proposes adding a new API to expose supported power states of
    nodes. This API would be helpful to see if a power action is supported
    by a node because it depends on whether a power interface supports
    power actions such as soft power off and soft reboot.
