1. I think the instructions in step 2 of the security section which describe adding the CA to server/client truststores are swapped. That is, the instruction that says to add the CA to the server truststore adds it to the client truststore (and vice versa).
2. "clients keys" should be possessive ("clients' keys").

ijuma said that it would make sense to split out this work from KAFKA-3234, since KAFKA-3234 had both a mechanical change (generating docs) as well as a change requiring discussion (deprecating/renaming config options).
jjkoshy, I hope you don't mind that I took over this work. It's been 3 months since the last activity on KAFKA-3234, so I thought it would be okay to take over.
This work is essentially is the first 5-6 commits from Joel's https://github.com/apache/kafka/pull/907. However, since I'm not very experienced with git, I didn't do a direct merge/rebase, but instead largely hand-merged it. I did some minor cleanup. All credit goes to Joel, all blame goes to me. :)
For reference, I attached the auto-generated configuration.html file (as a PDF, because github won't let me attache html).
[configuration.pdf](https://github.com/apache/kafka/files/323901/configuration.pdf)
This is my first time writing Scala, so let me know if there are any changes needed.
I don't know who is the right person to review this. ijuma, can you help me redirect this to the appropriate person? Thanks.

I've updated the ops documentation with information on using the XFS filesystem, based on LinkedIn's testing (and subsequent switch from EXT4).
I've also added some information to clarify the potential risk to the suggested EXT4 options (again, based on my experience with a multiple broker failure situation).

The reasons to remove it are:
1. It's currently broken. The purpose of the [JIRA](https://issues.apache.org/jira/browse/KAFKA-3761) was to report that the RunningAsController state gets overwritten back to "RunningAsBroker".
2. It's not a useful state.
a. If clients want to use this metric to know whether a broker is ready to receive requests or not, they do not care whether or not the broker is the controller
b. there is already a separate boolean property, KafkaController.isActive which contains this information.
