Review request for kylin, Dayue Gao, Dong Li, hongbin ma, and Wang Xiaoyu.


Bugs: KYLIN-3061
    https://issues.apache.org/jira/browse/KYLIN-3061


Repository: kylin


Description
-------

There are two bugs in this issue.

First
1. Choose one streaming table, choose the 'Streaming Cluster' tab, then click 
'Edit' button
2. The edit page will be opened, then you can edit the value of topic of 'Kafka 
Setting'. As long as you modify the ID, Host, Port value, the original value 
tag will follow changes
3. When you click 'cancel' button, you will find the old values have been 
changed to the new values, and if you click the 'submit' button, you will also 
find the values to be canceled will be submitted
But I think the correct way should be that 'cancel' button will not change any 
value.

Second
The follow code in streamingConfig.js has a bug, even if "cluster.newBroker" 
object matchs the one element of "cluster.brokers" array, this "if" decision 
will return false. Because even though the "cluster.newBroker" object has the 
same attribute values as an element in the array, their storage addresses may 
be different. The result is that you can add several same record, like 
can_add_the_same_record.png.
  $scope.saveNewBroker = function(cluster) {
    if (cluster.brokers.indexOf(cluster.newBroker) === -1) {
    ......
    }
  }
  
So I have repaired these two bugs, please check the patch, thanks!
