[Openstack-operators] Keystone Configuration in HA: bind_host

Hi Alvise,

bind_host IP means the api server will only listen for requests to that IP
address. You can check it with sudo netstat -ntlp

bind_host will always work no matter you are configuring for HA or
not. Because means listen on all IP on localhost.
bind_host <local_ip> is hardly useful for HA. Because in HA setup, you
probably use vip in endpoint registration.
