SigNoz needs a cluster named with

Thanks a lot @Ankit Nayan and @Srikanth Chekuri. Really really appreciate your help. It is now working. You guys are rock. Now I will change zooker because I want to use using clickhouse-keeper. and will change query service endpoint to point to my external database
