The CAddrInfo is a class that already exists in the node software.
This will cause compiler issues as the seeder is built with more parts
of the node software. Because the seeder does not record the same
information about an address as the node software, refactoring the
seeder's version of the class to inherit the node software's version
would not be useful.
