Description

The packages related to the DockerLinuxContainerRuntime all exceed the 80 char line length limit enforced by checkstyle. This causes every build to fail with a -1. I would like to exclude this rule from causing a failure.

Alternatively, we could look to restructure the packages here, but I question what value this check really provides.
