90ec97743b streaming: Introduce get_stream_result_future
Stream manager tracks two kind of streams: initiated or receiving. Give
a plan_id, search both lists to get a stream_result_future instance.

3a5af0a7fb streaming: Fix stream_coordinator::is_receiving
Unlike Origin, We can not use _connections_per_host == 0 to indicate we
are a follower since we set _connections_per_host to 1 for follower too.

4d06c2aa1d Move to_partition_range() adaptor to global scope
It should be moved to i_partitioner.hh, but to do that range<> has to
be first moved out of query-request.hh to break cyclic dependency.
I didn't want to cause conflicts with in-flight patches to range<>.

e5feff5d71 dht: ring_position: Switch to total ordering
range::is_wrap_around() and range::contains() rely on total ordering
on values to work properly. Current ring_position_comparator was only
imposing a weak ordering (token positions equal to all key positions
with that token).

range::before() and range::after() can't work for weak ordering. If
the bound is exclusive, we don't know if user-provided token position
is inside or outside.

Also, is_wrap_around() can't properly detect wrap around in all
cases. Consider this case:

 (1) ]A; B]
 (2) [A; B]

For A = (tok1) and B = (tok1, key1), (1) is a wrap around and (2) is
not. Without total ordering between A and B, range::is_wrap_around() can't
tell that.

I think the simplest soution is to define a total ordering on
ring_position by making token positions positioned either before or
after all keys with that token.

54d482afe4 streaming: Test both pushing and pulling of data
stream_plan.transfer_ranges() sends data from local to remote node.

stream_plan.request_ranges() asks remote to send data to local.

After streaming, both nodes contains all the keys.

5e6f84cba8 streaming: Implement stream_result_future::handle_session_prepared
Instead of playing the game of casting between stream_event and derived
class. We overload handle_stream_event with derived stream_event class.

virtual void handle_stream_event(session_complete_event event) {}
virtual void handle_stream_event(progress_event event) {}
virtual void handle_stream_event(session_prepared_event event) {}

Also, make the virtual function non pure virtual, so user can override
the interested event only without defining all of the three.
