in tor-scale setup, discovery-servers subscriber list did not show the entire list

[Vedamurthy Joshi]

R2.20 Build 30 Ubuntu 14.04 Juno multi-node setup

In this tor-scale setup, there are 4 tor-agent-nodes having 64 tor-agents each(nodei38, nodei28, nodei37, nodei30) and a compute node (nodei27)

It was seen today that http://nodei35:5998/clients didnt any of the subscription from these tor-agent-nodes (could see less than 100 entries)
nodei28 was out of network at that time.
nodei28 was later brought online, and only its subscriptions are seen now.

Per Deepinder, discovery server is limiting client count to 100 while displaying/returning.

But it still doesnt explain how less than 100 entries were seen earlier in the day. Logging the bug anyhow
Discovery logs from the logs will be in http://10.204.216.50/Docs/bugs/#

Allowed Cassandra to fetch more columns.
