Incorrect openstack host in dashboard settings

ISO: {"build_id": "2014-07-28_00-31-14", "mirantis": "yes", "build_number": "149", "ostf_sha": "09b6bccf7d476771ac859bb3c76c9ebec9da9e1f", "nailgun_sha": "3f19a97e4f250c49742655ef94edd6e33cc9845a", "production": "docker", "api": "1.0", "fuelmain_sha": "9aa2e3f4d60337a4fa75b0dd9e1c904dc1221102", "astute_sha": "6db5f5031b74e67b92fcac1f7998eaa296d68025", "release": "5.0.1", "fuellib_sha": "19acf67997492580beede54d54895c876e1f3f18"}

Steps To Reproduce:
1. Install Openstack in HA mode (Ubuntu, 3 controllers, 1 compute, 1 ceph, Neutron GRE)
2. Login to Horizon dashboard.

Actual Result:
On controllers in file /etc/openstack-dashboard/local_settings.py we can see that OPENSTACK_HOST specified IP of the first controller instead cloud public IP.

In the result we can see the HA doesn't work because we have 3 controllers with Horizon, which configured to use API from the first controller. In case of all HA nodes active it will work, but when first controller will going offline we will lost connectivity to Horizon dashboard: we can't login to dashboard and perform any actions, because all API requests will be send to the first contrller.

We can easily fix this issue, need to set VIP address istead of address of first controller in Horizon config:
OPENSTACK_HOST="VIP of OpenStack cloud in HA mode"

inter-services communications configured with Management VIP (internal_virtual_ip), thus the same is used for OPENSTACK_HOST:
