    Get all needed instances for volumes attachments at Admin->Volumes

    Nova server_list() wrapper needs to receive an explicit `all_tenants`
    boolean flag in order to request instances for _all_ tenants -
    otherwise while rendering Admin->Volumes table Django will request
    missing instances (to get their names for volume attachments) one by
    one, thus significantly increasing response time.

    This patch adds check if all_tenants in search_opts and add it to
    the search else uses tenant_id in the search_opts.
