Must have a role named Controller running memcached when using custom roles due to hardcoded ControllerIpListMap

[James Slagle]

In overcloud.j2.yaml there is:

      # FIXME(shardy): These require further work to move into service_ips
      memcache_node_ips: {get_attr: [ControllerIpListMap, net_ip_map, {get_attr: [ServiceNetMap, service_net_map, MemcachedNetwork]}]}

The hardcoded resource name ControllerIpListMap means that a role named "Controller" must be present and it should be running the memcached service given we are adding its ip to memcache_node_ips.

The FIXME is probably meant to address this issue, but I did not see a bug filed, so that's why I'm filing one.

Thanks, yeah I meant to get to this and never did - we'll need to address this in puppet-tripleo in a similar way to how we assemble the ipv6 lists for ceph.
