To make `kompose up` & `kompose convert` equal in feature, This PR will
add `--controller` flag for `kompose up` as well as `kompose down`
so that user experience will be the same for `up` & `convert`
Resolves #798

since we are adding `--controller` to `up` and `down`, So respective code to deploy and undeploy also being added for `daemonset` and `replicationcontroller`
