Add floating IP support for vrouter NICs

[Michal Opala]

Description

OpenNebula supports automatic floating IP (VIP) pre-allocation for vrouter instances. It can be enabled by adding FLOATING_IP = "YES" to NIC blocks. The allocated VIP values are passed to vrouter instances via ETHx_VROUTER_IP context variables, then VRRP decides which vrouter instance should host the VIPs. This issue is about implementing this missing feature.
