Change DnsTlsTransport to store a copy of a query

This is preparation for configurable per-query timeout in order to
allow a lookup thread to exit while a DnsTlsSocket loop thread is
still waiting the response. Since a DnsTlsTransport instance is
accessible to both lookup threads and a DnsTlsSocket loop thread, change
it to store a copy of a query in case of any operation needed for
the query in the loop thread; for example, the response arrives after
timeout.
