Currently, data structures used in manager.hh use their own aliases for gms::inet_address. It is clear they all should use the same type and having different names for it only reduces readability of the code. This commit introduces a common alias -- endpoint_id -- and gets rid of the other ones. This commit is also the first step in modularizing manager.hh by extracting common types to another file.
