Tests - IP allocation - new test that shows current LCP2 failure
There are 4 IPs across 2 nodes and 2 addresses across 2 other nodes.
If one of the latter nodes is unhealthy and then becomes healthy
again, an IP isn't failed back. This is because the nodes in the 1st
group are >= unbalanced then the nodes in the 2nd group.
