a new set of dynamic checks

[TomasTomecek]

We would like to start a new group of generic dynamic checks on containers. One of the use cases is to run shell inside and check whether the container is running, e.g.:

$ docker run -t --rm -d --name asd $image sh
$ docker ps | grep asd

We should check for these cases:

• [ ] docker run -d -t $image bash
• [ ] docker run -d $image sleep infinity && docker exec ...

• [ ] ~~Run the image with what is specified in usage label~~ usage label is not required, so we cant test this on all images
