compose-file: remove reference to custom init path

thaJeztah · thaJeztah · commit a6fe6f7f68a2 · 2019-04-11T10:43:26.000+02:00
This option was never functional, and was not intended to be added to the "container create" API, so let's remove it, because it has been removed in Docker 17.05, and was broken in versions before that; see - docker/docker-py#2309 Remove init_path from create - moby/moby#32355 --init-path does not seem to work - moby/moby#32470 remove --init-path from client Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
