OCPBUGS-43724: Fix Load balancer IP setup

[rna-afk]

Fixing the issue where the load balancer IP was not set in the range of the machine network CIDRs by setting it to the first IP in the CIDR range.

Also extending this logic to non-existing vnet installs since the problem can happen even during normal installs.
