Keystone interface address and memcached override

Browse Source 
Note: This should not result in any behavior changes in regular Kolla,
just Kolla-Kubernetes and only when you've overridden stuff in globals.yml

Allows override of interface address and memcached pools, so that
Kubernetes can do the right thing.

There are some significant architectural issues involved in
memcached pooling in the Kolla-kubernetes world.  Avoiding them right
now.

Current working Kolla-Kubernetes globals.yml file, assuming that your
memcached servers are available under the DNS alias "memcached":

api_interface_address: "0.0.0.0"

memcached_servers: "memcached"

keystone_database_address: "mariadb"
keystone_admin_url: "{{ admin_protocol }}://keystone-admin:{{ keystone_admin_port }}/v3"
keystone_internal_url: "{{ internal_protocol }}://keystone-public:{{ keystone_public_port }}/v3"
keystone_public_url: "{{ public_protocol }}://keystone-public:{{ keystone_public_port }}/v3"
