Cascading TS repl inefficiency [JIRA: RIAK-3132]

[macintux]

Upon a casual reading, it appears that I'm unnecessarily re-wrapping objects in the w3 wire format for cascading replication.

riak_repl/src/riak_repl2_rtsink_conn.erl

Lines 305 to 308 in 23915a3

	%% Timeseries data is an encoded tagged tuple
	rtq_push(_Binary, {ts, PartIdx, Batch}, Meta) ->
	riak_repl2_rtq:push(length(Batch),
	riak_repl_util:to_wire(w3, {PartIdx, Batch}), Meta).

I suspect the first parameter, Binary, is equivalent to the result from riak_repl_util:to_wire(w3, {PartIdx, Batch}).
