* Rolling kill-restart Streams instances with brokers unavailable temporarily, and validate that the streams can still complete the restart process
Reviewers: Bill Bejeck <bill@confluent.io>, Matthias J. Sax <matthias@confluent.io>
System test for two cases:
* Starting a multi-node streams application with the broker down initially, broker starts and confirm rebalance completes and streams application still able to process records.
* Multi-node streams app running, broker goes down, stop stream instance(s) confirm after broker comes back remaining streams instance(s) still function.

Allow Connect Service in system tests to start asynchronously.
Specifically, allow for three startup conditions:
1. No condition - start async and return immediately.
2. Semi-async - start immediately after plugins have been discovered successfully.
3. Sync - start returns after the worker has completed startup. This is the current mode, but its condition is improved by checking that the port of Connect's REST interface is open, rather than that a log line has appeared in the logs.
An associated system test run has been started here:

Increase the number of messages produced to make the test more reliable. The test failed in a recent build and also fails intermittently when run locally. Since the producer uses acks=0 and the test stops as soon as a lag is observed, the change shouldn't have a big impact on the time taken to run when lag is observed sooner.

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.

Closes#3725 from dguy/fix-system-test
When a Connect distributed worker starts up talking with broker versions 0.10.1.0 and later, it will use the AdminClient to look for the internal topics and attempt to create them if they are missing. Although the AdminClient was added in 0.11.0.0, the AdminClient uses APIs to create topics that existed in 0.10.1.0 and later. This feature works as expected when Connect uses a broker version 0.10.1.0 or later.
However, when a Connect distributed worker starts up using a broker older than 0.10.1.0, the AdminClient is not able to find the required APIs and thus will throw an UnsupportedVersionException. Unfortunately, this exception is not caught and instead causes the Connect worker to fail even when the topics already exist.
This change handles the UnsupportedVersionException by logging a debug message and doing nothing. The existing producer logic will get information about the topics, which will cause the broker to create them if they don’t exist and broker auto-creation of topics is enabled. This is the same behavior that existed prior to 0.11.0.0, and so this change restores that behavior for brokers older than 0.10.1.0.
This change also adds a system test that verifies Connect works with a variety of brokers and is able to run source and sink connectors. The test verifies that Connect can read from the internal topics when the connectors are restarted.
