Remove log4j (#304)

* feat: Add ability to specify endpoint in CPS connector.

* Set default endpoint.

* Add note about low throughput when using partition

* fix: Actually set endpoint provided by command-line
argument

* fix: Allow one to specify unordered delivery

* Remove log4j usage and Kafka testing so we can remove the log4j dependency entirely.
