Optional floating IPs in cluster machines

[bartekle]

/kind feature

Describe the solution you'd like Possibility to associate floating IP with default port of cluster machine.

Anything else you would like to add: This feature may be redundant in case of debuging and bastion host availability, but floating IP is also used as egress strategy - node has other, specific network path rather than default network nodes.

Is this different to the functionality provided by the floating IP IPAM provider?
