Closes-Bug: #1713592 - Changing validations of Openstack HA - external VIP mandatory

Now the validations are:

Single interface:-

If more than one openstack node:
External vip is mandatory.
If internal vip is given, it should be same as external vip

Multiple interface:-

If more than one openstack node:
Both internal and external vips are mandatory.
They cannot be the same.

Patch 2:

In single interface, check case where internal vip also given
