**NOTE: This should be backported to the `1.1` branch, and is currently a blocker for 1.1.**
The `connect_test.py::ConnectStandaloneFileTest.test_file_source_and_sink` system test is failing with the SASL configuration without a sufficient explanation. During the test, the Connect worker fails to start, but the Connect log contains no useful information. There are actual several things compounding to cause the failure and make it difficult to understand the problem.
First, the `tests/kafkatest/tests/connect/templates/connect_standalone.properties` is only adding in the broker's security configuration with the `producer.` and `consumer.` prefixes, but is not adding them with no prefix. The worker uses the AdminClient to connect to the broker to get the Kafka cluster ID and to manage the three internal topics, and the AdminClient is configured via top-level properties. Because the SASL test requires the clients all connect using SASL, the lack of broker security configs means the AdminClient was attempting and failing to connect to the broker. This is corrected by adding the broker's security configuration to the Connect worker configuration file at the top-level. (This was already being done in the `connect_distributed.properties` file.)
Second, the default `request.timeout.ms` for the AdminClient (and the other clients) is 120 seconds, so the AdminClient was retrying for 120 seconds before it would give up and thrown an error. However, the test was only waiting for 60 seconds before determining that the service failed to start. This can be corrected by setting `request.timeout.ms=10000` in the Connect distributed and standalone worker configurations.
Third, the Connect workers were recently changed to lookup the Kafka cluster ID before it started the herder. This is unlike the older uses of the AdminClient to find and manage the internal topics, where failure to connect was not necessarily logged correctly but nevertheless still skipped over, relying upon broker auto-topic creation to create the internal topics. (This may be why the test did not fail prior to the recent change to always require a successful AdminClient connection.) Although the worker never got this far in its startup process, the fact that we missed such an error since the prior releases means that failure to connect with the AdminClient was not being properly reported.
The `ConnectStandaloneFileTest.test_file_source_and_sink` system tests were run locally prior to this fix, and they failed as with the nightlies. Once these fixes were made, the locally run system tests passed.

Currently port forwarding is setup for HttpMetricsCollector when the Service's start_node method is called, but not canceled during stop. This hasn't presented a problem so far because we don't have tests that use this *and* restart the service. However, if a test/service does that, it will throw an exception since the port is already bound.
This just does the cleanup when stopping so a subsequent attempt to start again will succeed.
https://jenkins.confluent.io/job/system-test-kafka-branch-builder/1320 is a test run for a Test that uses ProducerPerformanceService, which in turn uses HttpMetricsCollector to validate the change.

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.
