    KAFKA-3144: Report members with no assigned partitions in 
ConsumerGroupCommand

    This PR makes a couple of enhancements to the `--describe` option of 
`ConsumerGroupCommand`:
    1. Listing members with no assigned partitions.
    2. Showing the member id along with the owner of each partition (owner is 
supposed to be the logical application id and all members in the same group are 
supposed to set the same owner).
    
    Note: The third request on the corresponding JIRA (listing group active 
offsets for groups with no members for the new consumer) is not implemented as 
part of this PR.
    I suggest moving that into a separate JIRA as it seems to be a more 
involved change and potentially requires making changes to the server side too.

You can merge this pull request into a Git repository by running:

    $ git pull https://github.com/vahidhashemian/kafka KAFKA-3144

> A couple of suggestions on improving ConsumerGroupCommand. 
> 1. It would be useful to list members with no assigned partitions when doing 
> describe in ConsumerGroupCommand.
> 2. Currently, we show the client.id of each member when doing describe in 
> ConsumerGroupCommand. Since client.id is supposed to be the logical 
> application id, all members in the same group are supposed to set the same 
> client.id. So, it would be clearer if we show the client id as well as the 
> member id.
