Docker Command Line Executor

• using Docker Containers is a nice way to solve several problems
  • installation of third party converters is easier
  • we have a better isolation
• we can use Docker from the CommandLineExecutor but this is not ideal
  • we are using CommandLine API and Extension Point rather than the native Docker API and a custom tailored Extension Point
  • we have no fallback if Docker is not there

So, the goal of this Epic is :

• Build a DockerExecutor using Docker API
• Provide Docker Images for the converters we need
• Handle the Fallback from Docker to native ComnmandLine
