Tomasz Grabiec e989d65539 dht: Make ring_position_view copyable
dht::token needs to be stored as a pointer now and not a reference so
that validity of old pointers is not impacted by in-place object
construction which would occur in the copy-assignment operator.

[1] says that old pointers can be used to access the new object only
if the type "does not contain any non-static data member whose type is
const-qualified or a reference type".
