    Make scheduler_hints schema allow list of id

    Nova v2.0 API allows a list of server_id, and the corresponding
    filter handles it. However, Nova v2.1 API doesn't do that now.
    That is backward incompatibile issue.
    This patch fixes this issue.

    NOTE: Tempest patch Ib3365ac2783a0578c7a1a1e72d9b6c9cfea340f5
          is for reproducing this problem on the gate.
          After this fixing, the Tempest patch can be merged and
          we will be able to block this problem.

This issue was fixed in the openstack/nova 12.0.1 release.

[OpenStack Infra (hudson-openstack)]

Change abandoned by Ken'ichi Ohmichi (<email address hidden>) on branch: master
Review: https://review.openstack.org/253012
Reason: Sorry, but this patch becomes unnecessary now and needs to be abandoned for making the review queue small.

[Thierry Carrez (ttx)]

This issue was fixed in the openstack/nova 13.0.0.0b2 development milestone.
