This resolves the following issues in the ProcessorTopologyTestDriver:
- It should not create an internal changelog topic when using `through()` and `table()`
- It should forward the produced record back into the topology if it is to a source topic

There were some minor differences in the basic consumer config and streams config that are now rectified. In addition, in AWS environments the socket size makes a big difference to performance and I've tuned it up accordingly. I've also increased the number of records now that perf is higher.

This applies to new-consumer based groups and would avoid scenarios in which user issues a `--describe` query while the group is initializing.
Example: The following could occur for a newly created group.
```
kafkakafka:~/workspace/kafka$ bin/kafka-consumer-groups.sh --bootstrap-server localhost:9092 --describe --group g
Note: This will only show information about consumers that use the Java consumer API (non-ZooKeeper-based consumers).
Error: Executing consumer group command failed due to The group coordinator is not available.
```
With this PR the group is queried repeatedly at specific intervals within a preset (and configurable) timeout `group-init-timeout` to circumvent unfortunate situations like above.

added \<pre> tags to not break javadoc display of the ASCII diagrams.
see broken ascii here:
https://kafka.apache.org/0102/javadoc/org/apache/kafka/streams/KafkaStreams.State.html
fix can be checked with gradle :streams:javadoc and then checking streams/build/docs/javadoc/org/apache/kafka/streams/KafkaStreams.State.html
I also fixed the diagram in StreamThread.java however currently no javadoc is generated for that one (since it's internal)

The consumer properties get logged twice since two instances
of ConsumerConfig are created during creation of KafkaConsumer.
I added a constructor of ConsumerConfig accepting the boolean
parameter doLog which is already passable in AbstractConfig
and set it to false during the second ConsumerConfig creating
in the KafkaConsumer constructor.

The phase_two security upgrade test verifies upgrading inter-broker and client protocols to the same value as well as different values. The second case currently changes inter-broker protocol without first enabling the protocol, disrupting produce/consume until the whole cluster is updated. This commit changes the test to be a non-disruptive upgrade test that enables protocols first (simulating phase one of upgrade).

Closes#2578 from Kamal15/config
It contained this step:
val canShutdown = isShuttingDown.compareAndSet(false, true)
if (canShutdown && shutdownLatch.getCount > 0) {
without any fallback for the case of `shutdownLatch.getCount == 0`. So in the case
of `shutdownLatch.getCount == 0` (when a previous call to the shutdown method
was right about to finish) you would set `isShuttingDown` to true again without any
possibility of ever getting the server started (since `startup` will check
`isShuttingDown` before setting up a new latch with count 1).
Long story short: concurrent calls to shutdown can get the server locked in a broken state.
This fixes the reported error:
java.lang.IllegalStateException: Kafka server is still shutting down, cannot re-start!
