An IPv4 config (for a domain/interface of the router) consists of an IPv4 address, a subnet prefix specifier, an optional gateway IPv4 address, and some flags that declare whether these fields and the config as a whole are valid. To make the handling of those tightly connected values easier and less error prone, we encapsulate them in a new class. Ref #2534
