bug: kill topology failed by thrift in no-leader nimbus

["daxwang (王文军)" <da...@tencent.com>]

in storm-1.0.3 cluster,  there have 2 nimubs, i kill topology by thrift api killTopologyWithOpts.  i found it can kill succussfully in leader nimbus, but failed in no leader nimbus.
maybe it's a bug

my python thrift version: thrift==0.9.2
