[consensus_peers] micro-optimization on controller status
While running raft_consensus_stress-itest where a lot of RPC fail,
I found the following stats for operator new[](unsigned long)
in tserver with regard of Status::CopyState():
- 1.13% kudu-tserver libtcmalloc.so.4.5.1 [.] operator
new[](unsigned long)
- operator new[](unsigned long)
...
+ 3.21% kudu::Status::CopyState(char const*)
kudu::Status::Status(kudu::Status const&)
kudu::rpc::OutboundCall::status() const
kudu::rpc::RpcController::status() const
kudu::consensus::Peer::ProcessResponse()
...
Of course, that's not in the hot path in case of success scenarios,
but I think it makes sense to add these micro-optimizations.
