Petr Gusev 63f64f3303 token_metadata: make it a template with NodeId=inet_address/host_id
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.
