The number of Kafka is incorrect

[wu-sheng]

In this topology, these is only one Kafka, and same in reality env.

I have pinpointed this issue. We really need to refact all component libraries. This is an agent issue, caused by old design. @peng-yongsheng @ascrutae

@wu-sheng I guess you have found the root cause of the issue. Could you please describe your findings?

@ajanthan Look like you are facing this issue too. I can explain to you with more details. The reason I called this a design issue, it is in old days(3.x series), we have no such a powerful UI, just topology. Then in order to visualize conjecture nodes(such as: MySQL, Kafka, which would be installed an agent), we put the client library names as the server name.

For example, we set component name of Kafka consumer as Kafka, only, which triggers the issue described in here.

So we have to change this, and put the real component names in agent, then do component->server-side mapping for the UI.

See #1266 , that includes all the changes for this issue. But sadly, today's travis-ci has some network issues... fails all the time... can't merge it.
