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.
