NodeId is used in all internal token_metadata data structures, that previously used inet_address. We choose topology::key_kind based on the value of the template parameter. generic_token_metadata::update_topology overload with host_id parameter is added to make update_topology_change_info work, it now uses NodeId as a parameter type. topology::remove_endpoint(host_id) is added to make generic_token_metadata::remove_endpoint(NodeId) work. pending_endpoints_for and endpoints_for_reading are just removed - they are not used and not implemented. The declarations were left by mistake from a refactoring in which these methods were moved to erm. generic_token_metadata_base is extracted to contain declarations, common to both token_metadata versions. Templates are explicitly instantiated inside token_metadata.cc, since implementation part is also a template and it's not exposed to the header. There are no other behavioral changes in this commit, just syntax fixes to make token_metadata a template.
