[CE] no graceful removal of query node

Not able to see graceful removal of query node on community edition

To repro:

• setup 3 node cluster with data,index,query
• load travel-sample
• run long query e.g.
  with TR as (select * from `travel-sample` union select * from `travel-sample` union select * from `travel-sample` union select * from `travel-sample`) select count from TR;
• from node1 remove node3:
  couchbase-cli rebalance -c localhost -u Administrator -p password --server-remove 172.23.104.92:8091

From cbq, query is canceled:

cbq> with TR as (select * from `travel-sample` union select * from `travel-sample` union select * from `travel-sample` union select * from `travel-sample`) select count(*) from TR;
