There are more methods that had to be touched than I anticipated when writing [the KIP](https://cwiki.apache.org/confluence/display/KAFKA/KIP-215%3A+Add+topic+regex+support+for+Connect+sinks).
The implementation here is now complete and includes a test that verifies that there's a call to `consumer.subscribe(Pattern, RebalanceHandler)` when `topics.regex` is provided.

The ConnectExceptionMapper was originally intended to handle ConnectException errors for some expected cases where we just want to always convert them to a certain response and the ExceptionMapper was the easiest way to do that uniformly across the API. However, in the case that it's not an expected subclass, we should log the information at the error level so the user can track down the cause of the error.
This is only an initial improvement. We should probably also add a more general ExceptionMapper to handle other exceptions we may not have caught and converted to ConnectException.

1. Add The AdminClient into Kafka Streams, which is shared among all the threads.
2. Add ADMIN_PREFIX to StreamsConfig.
3. Also made a few tweaks on the metrics of the AdminClient, which is slightly different from the StreamsKafkaClient (note these changes will not be reflected in this PR but only take place when we eventually replace StreamsKafkaClient):
3.1. "clientId" tag will be set as "clientId-admin": in StreamsKafkaClient it is whatever user sets, and hence could even be null.
3.2. "groupPrefix" will be set as "admin-client": in StreamsKafkaClient it will be "kafka-client".
So the metrics from `StreamsKafkaClient` to `AdminClient` would be changed from
`kafka.admin.client:type=kafka-client-metrics,client-id=`
to
`kafka.admin.client:type=admin-client-metrics,client-id=myApp-UUID-admin`

This is follow up to #4072 which added the PushHttpMetricsReporter and converted some services to use it. We somehow missed some compatibility issues that made the ProducerPerformance tool fail when using a newer tools jar with older common/clients jar, which we do with some system tests so we have all the features we need in the tool but can build compatibility tests for older releases.
This just adjusts some API usage to make the tool compatible with all previous releases.

ZooKeeperClient is a zookeeper client that encourages pipelined requests to zookeeper. We want to add the notion of max inflight requests to the client for several reasons:
1. to bound memory overhead associated with async requests on the client.
2. to not overwhelm the zookeeper ensemble with a burst of requests.

Closes#3860 from onurkaraman/KAFKA-5894
We only need to generate the event when the znode is created or deleted.
In the former case, we start the reassignment while in the latter we
re-register the watcher (necessary for the Controller to detect future
reassignments).
During Controller failover, we restart the reassignment without generating
an event so it's not affected by this change.
Also use the Controller cache (`ControllerContext.partitionsBeingReassigned`)
in `removePartitionFromReassignedPartitions` instead of reloading the
data from ZooKeeper.
Overall, we would previously load the reassignment data from ZooKeeper twice
per completed partition whereas now as don't do it at all. As an example,
say there were 30k partitions being reassigned, these changes save the
allocation of 900 million `TopicAndPartition` and `Seq[Int]` (replicas)
instances (could easily amount to 20-40 GB depending on the topic name
length). This matters most in cases where the partitions being reassigned
don't have much data allowing the reassignment to complete reasonably
fast for many of the partitions.
