docker_container: fix init check requirements (#40839)

Browse source 
* docker_container: ensure 'init' is supported

Check docker-py version too.

Move API version check in docker_container module since 'init' module
parameter isn't defined by other docker modules.

docker-py supports 'init' since 2.2.0:
https://github.com/docker/docker-py/blob/2.2.0/docs/change-log.md

* docker_container: fix compat with docker-py<2.2

Exception was:
TypeError: create_host_config() got an unexpected keyword argument 'init'
