On Windows, the following output is seen when starting Zookeeper and Kafka servers:
```
'#' is not recognized as an internal or external command,
operable program or batch file.
```
This pull request makes a minor correction to the Windows `kafka-run-class.bat` script to replace the use of `#` with `rem`.

guozhangwang enothereska mjsax miguno please take a look. A few things that need to be clarified
1. I've added StreamsConfig.USER_ENDPOINT_CONFIG, but should we have separate configs for host and port or is this one config ok?
2. `HostState` in the KIP has a byte[] field - not sure why and what it would be populated with
3. I've changed the API to return `List<KafkaStreamsInstance>` as opposed to `Map<HostInfo, Set<TaskMetadata>>` as i find this far more intuitive to work with.

kafka-run-class.sh now runs under Cygwin; paths and classpath are set up properly.
**WARNING:** The script was not tested on a Linux machine, only under Cygwin. Prior to merge it into trunk, if accepted, please run a quick test to ensure nothing broke. From my own code review, there should not be any problem, but we can never be too sure.
I do not have the environment to test it under Linux at this moment.

ewencp I went down the list of connect configs and it looks like only the internal converter configs are mismarked. It looks like the `cluster` config that is present in the current docs is already gone. The only other values I can see arguing to change importance on are the ssl configs (marked high) but they are consistent with the producer/consumer config docs so that's at least consistent. Everything else marked high looks either mandatory or requires consideration in a production deployment to me.

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 affirm that the contribution is my original work and that I license the work to the project under the project's open source license.
This cleans up misbehaviour that was introduce while fixing KAFKA-3817. It is impossible for a non-count aggregate to be build, when the addition happens before the removal. IMHO making sure that these details are correct is very important.
This PR has local test errors. It somehow fails the ResetIntegrationTest. It doesn't quite appear to me why but it looks like this PR breaks it, especially because the error appears with the ordering of the events. Still I am unable to find where I could have broken it. Maybe not seems to fail on trunk aswell.

Closes#1705 from Kaiserchen/KAFKA-3817-preserve-order-for-aggreagators
1. The IllegalStateException is actually thrown from testCloseWithZeroTimeoutFromSenderThread() due to a bug. We call producer.close() in the callback. Once the first callback is called, producing records in the callback will hit the IllegalStateException. This only pollutes the output, but doesn't fail the test. I fixed this by only calling producer.send() in the first callback.
2. It's not clear which test throws TimeoutException and it's not reproducible locally. One thing is that the error message in TimeoutException is mis-leading since the timeout is not necessarily due to metadata. Improved this by making the error message in TimeoutException clearer.
3. It's not clear what actually failed testSendNonCompressedMessageWithCreateTime(). One thing I found is that since we set the linger time to MAX_LONG and are sending small messages, those produced messages won't be drained until we call producer.close(10000L, TimeUnit.MILLISECONDS). Normally, 10 secs should be enough for the records to be sent. My only hypothesis is that since SSL is more expensive, occasionally, 10 secs is still not enough. So, I bumped up the timeout from 10 secs to 20 secs.

This is a regression caused by 0bb1d3ae.
After that commit, Streams no longer has a direct dependency on slf4j-log4j12, but zkclient
has a dependency on an older version of slf4j-log4j12, so we get a transitive dependency on
the older version.
The fix is to simply exclude the undesired dependencies from the zkclient dependency.

The `acks` config that is provided to console producer with `request-required-acks` comes with `all`, `-1`, `0`, `1` as valid options (`all` and `-1` being interchangeable). Currently, the console producer expects an integer for this input and that makes `all` to become an invalid input. This PR fixes this issue by changing the input type to String.

The KafkaStreamsTest can occasionally hang if the test doesn't run fast enough. This is due to there being no brokers available on the broker.urls provided to the StreamsConfig. The KafkaConsumer does a poll and blocks causing the test to never complete.
