NMSockAddrEndpoint is an immutable structure that contains the endpoint string of a service. It also includes the (naive) parsing of the host and port/service parts. This will be used for the endpoint of WireGuard's peers. But since endpoints are not something specific to WireGuard, give it a general name (and purpose) independent from WireGuard. Essentially, this structure takes a string in a manner that libnm understands, and uses it for node and service arguments for getaddrinfo(). NMSockAddrEndpoint allows to have endpoints that are not parsable into a host and port part. That is useful because our settings need to be able to hold invalid values. That is for forward compatibility (server sends a new endpoint format) and for better error handling (have invalid settings that can be constructed without loss, but fail later during the NMSetting:verify() step).
