It seems centos based images have wrong label info.

[root@kolla-k8s yum.repos.d]# docker inspect kolla/centos-binary-memcached:3.0.3 | jq .[0].Created
"2017-04-06T05:54:51.409325763Z"
[root@kolla-k8s yum.repos.d]# docker inspect kolla/centos-binary-memcached:3.0.3 | jq .[0].Config.Labels
{
  "build-date": "20170315",
  "kolla_version": "3.0.3",
  "license": "GPLv2",
  "name": "CentOS Base Image",
  "vendor": "CentOS"
}

This centos based kolla images was created at 2017-04-06.
But, in Labes infomation, build-date was set when CentOs Images was built.
and name, vendor also are implemented from the base centos image.
I think kolla shoud overwrite or delete these for exact information.
