Closes#390 from ijuma/kafka-2711
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)

* 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.

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,

resulting in race conditions. Add support for scheduling sequences of events

Let's say every consumer in a group has session timeout s. Currently, if a consumer leaves the group, the worst case time to stabilize the group is 2s (s to detect the consumer failure + s for the rebalance window). If a consumer instead can declare they are leaving the group, the worst case time to stabilize the group would just be the s associated with the rebalance window.
This is a low priority optimization!

This is a followup ticket from KAFKA-2084 to improve the windowSize calculation in Quotas. I've made the following changes:
1. Added a windowSize function on Rate
2. Calling Rate.windowSize in ClientQuotaManager to return the exact window size to use when computing the delay time.
3. Changed the window size calculation subtly. The current calculation had a bug wherein, it used the number of elapsed seconds from the "lastWindowSeconds" of the most recent Sample object. However, the lastWindowSeconds is the time when the sample is created.. this causes an issue because it implies that the current window elapsed time is always "0" when the sample is created. This is incorrect as demonstrated in a testcase I added in MetricsTest. I've fixed the calculation to count the elapsed time from the "oldest" sample in the set since that gives us an accurate value of the exact amount of time elapsed

As discussed in KAFKA-2419 - I've added a time based sensor retention config to Sensor. Sensors that have not been "recorded" for 'n' seconds are eligible for expiration.
In addition to the time based retention, I've also altered several tests to close the Metrics and scheduler objects since they can cause leaks while running tests. This causes TestUtils.verifyNonDaemonThreadStatus to fail.
