- Update installation method, following official installation
instructions.
- docker-engine was renamed to Docker CE around March 2017. Update
manpage to reflect that change.
- Remove flag `--experimental` since it is no longer necessary to install a
different binary to get experimental features. Experimental features are
included in the stable binary and can be enabled by a flag or in a
config file.
- Added state parameter for both types in the man.rst
- Changed --state absent behavior of __docker_compose
-- only remove docker-compose binary not whole docker
