Add support for skipping `docker-compose` v1 operations during Docker feature install script (#533)feature_docker-outside-of-docker_1.3.0feature_docker-in-docker_2.2.0

* Add support for skipping docker-compose operations

* Move changes from auto-generated files to templates and bump version

* Add test

* Add test conditions

* Add test conditions for docker-outside-of-docker

* install.sh set -x for debugging

* set -x

* Move compose-switch check in docker-outside-of-docker test

* Put into correct test

* Test for correct path
