             Summary: Refactor TopicCommand to remove redundant if/else 
statements
                 Key: KAFKA-4053
                 URL: https://issues.apache.org/jira/browse/KAFKA-4053
             Project: Kafka
          Issue Type: Improvement
          Components: admin
    Affects Versions: 0.10.0.1
            Reporter: Shuai Zhang
            Priority: Minor
             Fix For: 0.10.0.2


In TopicCommand, there are a lot of redundant if/else statements, such as
```val ifNotExists = if (opts.options.has(opts.ifNotExistsOpt)) true else 
false```

We can refactor it as the following statement:
```val ifNotExists = opts.options.has(opts.ifNotExistsOpt)```
