KAFKA-6060; Add workload generation capabilities to Trogdor
Previously, Trogdor only handled "Faults." Now, Trogdor can handle
"Tasks" which may be either faults, or workloads to execute in the
background.
The Agent and Coordinator have been refactored from a
mutexes-and-condition-variables paradigm into a message passing
paradigm. No locks are necessary, because only one thread can access
the task state or worker state. This makes them a lot easier to reason
about.
The MockTime class can now handle mocking deferred message passing
(adding a message to an ExecutorService with a delay). I added a
MockTimeTest.
MiniTrogdorCluster now starts up Agent and Coordinator classes in
paralle in order to minimize junit test time.
RPC messages now inherit from a common Message.java class. This class
handles implementing serialization, equals, hashCode, etc.
Remove FaultSet, since it is no longer necessary.
Previously, if CoordinatorClient or AgentClient hit a networking
problem, they would throw an exception. They now retry several times
before giving up. Additionally, the REST RPCs to the Coordinator and
Agent have been changed to be idempotent. If a response is lost, and
the request is resent, no harm will be done.

KAFKA-5142: Add Connect support for message headers (KIP-145)
**[KIP-145](https://cwiki.apache.org/confluence/display/KAFKA/KIP-145+-+Expose+Record+Headers+in+Kafka+Connect) has been accepted, and this PR implements KIP-145 except without the SMTs.**
Changed the Connect API and runtime to support message headers as described in [KIP-145](https://cwiki.apache.org/confluence/display/KAFKA/KIP-145+-+Expose+Record+Headers+in+Kafka+Connect).
The new `Header` interface defines an immutable representation of a Kafka header (key-value pair) with support for the Connect value types and schemas. This interface provides methods for easily converting between many of the built-in primitive, structured, and logical data types.
The new `Headers` interface defines an ordered collection of headers and is used to track all headers associated with a `ConnectRecord` (and thus `SourceRecord` and `SinkRecord`). This does allow multiple headers with the same key. The `Headers` contains methods for adding, removing, finding, and modifying headers. Convenience methods allow connectors and transforms to easily use and modify the headers for a record.
A new `HeaderConverter` interface is also defined to enable the Connect runtime framework to be able to serialize and deserialize headers between the in-memory representation and Kafka’s byte[] representation. A new `SimpleHeaderConverter` implementation has been added, and this serializes to strings and deserializes by inferring the schemas (`Struct` header values are serialized without the schemas, so they can only be deserialized as `Map` instances without a schema.) The `StringConverter`, `JsonConverter`, and `ByteArrayConverter` have all been extended to also be `HeaderConverter` implementations. Each connector can be configured with a different header converter, although by default the `SimpleHeaderConverter` is used to serialize header values as strings without schemas.
Unit and integration tests are added for `ConnectHeader` and `ConnectHeaders`, the two implementation classes for headers. Additional test methods are added for the methods added to the `Converter` implementations. Finally, the `ConnectRecord` object is already used heavily, so only limited tests need to be added while quite a few of the existing tests already cover the changes.

KAFKA-2366; Initial patch for Copycat
This is an initial patch implementing the basics of Copycat for KIP-26.
The intent here is to start a review of the key pieces of the core API and get a reasonably functional, baseline, non-distributed implementation of Copycat in place to get things rolling. The current patch has a number of known issues that need to be addressed before a final version:
* Some build-related issues. Specifically, requires some locally-installed dependencies (see below), ignores checkstyle for the runtime data library because it's lifted from Avro currently and likely won't last in its current form, and some Gradle task dependencies aren't quite right because I haven't gotten rid of the dependency on `core` (which should now be an easy patch since new consumer groups are in a much better state).
* This patch currently depends on some Confluent trunk code because I prototyped with our Avro serializers w/ schema-registry support. We need to figure out what we want to provide as an example built-in set of serializers. Unlike core Kafka where we could ignore the issue, providing only ByteArray or String serializers, this is pretty central to how Copycat works.
* This patch uses a hacked up version of Avro as its runtime data format. Not sure if we want to go through the entire API discussion just to get some basic code committed, so I filed KAFKA-2367 to handle that separately. The core connector APIs and the runtime data APIs are entirely orthogonal.
* This patch needs some updates to get aligned with recent new consumer changes (specifically, I'm aware of the ConcurrentModificationException issue on exit). More generally, the new consumer is in flux but Copycat depends on it, so there are likely to be some negative interactions.
* The layout feels a bit awkward to me right now because I ported it from a Maven layout. We don't have nearly the same level of granularity in Kafka currently (core and clients, plus the mostly ignored examples, log4j-appender, and a couple of contribs). We might want to reorganize, although keeping data+api separate from runtime and connector plugins is useful for minimizing dependencies.
* There are a variety of other things (e.g., I'm not happy with the exception hierarchy/how they are currently handled, TopicPartition doesn't really need to be duplicated unless we want Copycat entirely isolated from the Kafka APIs, etc), but I expect those we'll cover in the review.
Before commenting on the patch, it's probably worth reviewing https://issues.apache.org/jira/browse/KAFKA-2365 and https://issues.apache.org/jira/browse/KAFKA-2366 to get an idea of what I had in mind for a) what we ultimately want with all the Copycat patches and b) what we aim to cover in this initial patch. My hope is that we can use a WIP patch (after the current obvious deficiencies are addressed) while recognizing that we want to make iterative progress with a bunch of subsequent PRs.
