Closes#7477 from cmccabe/KAFKA-8984
Allow the Trogdor agent to execute external commands. The agent communicates with the external commands via stdin, stdout, and stderr.
Based on a patch by Xi Yang <xi@confluent.io>
Reviewers: David Arthur <mumrah@gmail.com>
* Allow the Trogdor agent to be started in "exec mode", where it simply
runs a single task and exits after it is complete.
* For AgentClient and CoordinatorClient, allow the user to pass the path
to a file containing JSON, instead of specifying the JSON object in the
command-line text itself. This means that we can get rid of the bash
scripts whose only function was to load task specs into a bash string
and run a Trogdor command.
* Print dates and times in a human-readable way, rather than as numbers
of milliseconds.
* When listing tasks or workers, output human-readable tables of
information.
* Allow the user to filter on task ID name, task ID pattern, or task
state.
* Support a --json flag to provide raw JSON output if desired.

KAFKA-7597: Add configurable transaction support to ProduceBenchWorker. In order to get support for serializing Optional<> types to JSON, add a new library: jackson-datatype-jdk8. Once Jackson 3 comes out, this library will not be needed.

Add threads with separate consumers to ConsumeBenchWorker. Update the Trogdor test scripts and documentation with the new functionality.
