Rescue any address errors logging them and ignoring the address. Update
how the host address is determined based on the network configuration.
Host address will be either the lowest address assignable via dhcp
configuration or first address available within the configured subnet.
Adds an override for the #read_network_interfaces when hostonlynetworks
are in use to properly identify the hostonly network information from
the guest. This also adjusts the IP provided for the network to be
the first in the subnet.
