add stdin_open, tty support, add tests, fix #344

This adds supports for stdin_open: bool and
tty: bool support for kubernetes and openshift
providers in kompose. This maps to the
template.Spec.Containers[0].Stdin and
template.Spec.Containers[0].TTY in Kubernets
world.

Also, added tests.

Fixes #344
