Closes#383 from granders/minor-systest-clock-skew
This has 2 fixes:
KAFKA-2664 - This patch changes the underlying map implementation of Metrics.java to a ConcurrentHashMap. Using a CopyOnWriteMap caused new metrics creation to get extremely slow when the existing corpus of metrics is large. Using a ConcurrentHashMap seems to speed up metric creation time significantly
KAFKA-2663 - Splitting out the throttleTime from the remote time. On throttled requests, the remote time went up artificially.
Some status on using a ConcurrentMap. Time to create :
- 100k sensors (1.5 seconds)
- 200k sensors (3 seconds)
- 400k sensors (9 seconds)
- 500k sensors (14 seconds)

KAFKA-2644 adds MiniKdc for system tests and hence needs a target to collect all MiniKdc jars. At the moment, system tests run `gradlew jar`. Replacing that with `gradlew systemTestLibs` will enable kafka jars and test dependency jars to be built and copied into appropriate locations. Submitting this as a separate PR so that the new target can be added to the build scripts that run system tests before KAFKA-2644 is committed. A separate target for system test artifacts will allow dependency changes to be made in future without breaking test runs.

There are several gauges in core that are registered but cannot be accessed programmatically. For example, gauges "LeaderCount", "PartitionCount", "UnderReplicatedParittions" are all registered in ReplicaManager.scala but there is no way to access them programmatically if one has access to the kafka.server object. Other metrics, such as isrExpandRate (also in ReplicaManager.scala) can be accessed. The solution here is trivial, add a var <variable name> in front of newGauge, as shown below
val partitionCount newGauge(
"PartitionCount",
new Gauge[Int] {
def value = allPartitions.size
}
)

This needs some refactoring to avoid the duplicated code between replication test and upgrade test, but in shape for initial feedback.
I'm interested in feedback on the added `KafkaConfig` class and `kafka_props` file. This addition makes it:
- easier to attach different configs to different nodes (e.g. during broker upgrade process)
- easier to reason about the configuration of a particular node
Notes:
- in the default values in the KafkaConfig class, I removed many properties which were in kafka.properties before. This is because most of those properties were set to what is already the default value.
- when running non-trunk VerifiableProducer, I append the trunk tools jar to the classpath, and run it with the non-trunk kafka-run-class.sh script

* A task id is now a class, ```TaskId```, that has a topic group id and a partition id fields.
* ```TopologyBuilder``` assigns a topic group id to a topic group. Related methods are changed accordingly.
* A state store uses the partition id part of the task id as the change log partition id.

* added ```PartitionGrouper``` (abstract class)
* This class is responsible for grouping partitions. Each group forms a task.
* Users may implement this class for custom grouping.
* added ```DefaultPartitionGrouper```
* our default implementation of ```PartitionGrouper```
* added ```KafkaStreamingPartitionAssignor```
* We always use this as ```PartitionAssignor``` of stream consumers.
* Actual grouping is delegated to ```PartitionGrouper```.
* ```TopologyBuilder```
* added ```topicGroups()```
* This returns groups of related topics according to the topology
* added ```copartitionSources(sourceNodes...)```
* This is used by DSL layer. It asserts the specified source nodes must be copartitioned.
* added ```copartitionGroups()```
* This returns groups of copartitioned topics
* KStream layer
* keep track of source nodes to determine copartition sources when steams are joined
* source nodes are set to null when partitioning property is not preserved (ex. ```map()```, ```transform()```), and this indicates the stream is no longer joinable

This adds coordination between DistributedHerders using the generalized consumer
support, allowing automatic balancing of connectors and tasks across workers. A
few pieces that require interaction between workers (resolving config
inconsistencies, forwarding of configuration changes to the leader worker) are
incomplete because they require REST API support to implement properly.

Closes#350 from ijuma/restore-ssl-consumer-test
Changes in this patch are:
1. ClientIdConfigHandler now passes through the config changes to the quota manager.
2. Removed static KafkaConfigs for quota overrides. These are no longer needed since we can override configs through ZooKeeper.
3. Added testcases to verify that the config changes are propogated from ZK (written using AdminTools) to the actual Metric objects.

The test required a specific sequence of events for each Consumer.poll() call,
but the MockConsumer.waitForPollThen() method could not guarantee that,
resulting in race conditions. Add support for scheduling sequences of events
even when running in multi-threaded environments.

This fix applies to three JIRAs, since they are all connected.
KAFKA-2459Connection backoff/blackout period should start when a connection is disconnected, not when the connection attempt was initiated
Backoff when connection is disconnected
KAFKA-2615Poll() method is broken wrt time
Added Time through the NetworkClient API. Minimal change.
KAFKA-1843Metadata fetch/refresh in new producer should handle all node connection states gracefully
I’ve partially addressed this for a specific failure case in the JIRA.

This PR implements SASL/Kerberos which was originally submitted by harshach as https://github.com/apache/kafka/pull/191.
I've been submitting PRs to Harsha's branch with fixes and improvements and he has integrated all, but the most recent one. I'm creating this PR so that the Jenkins can run the tests on the branch (they pass locally).
