Add bootstrap wrapper script for Docker
This allows users to pass "cli" or "run" as Docker CMD to easily switch modes without having to set environment variables. Also provides the DEBUG environment variable that used to be provided by the launcher script (which is no longer used as of this). Also removes the FORCE_JENKINS_CLI environment variables as it's no longer necessary. as per #207 (comment)
