provision/docker/docker: changed runContainer to also run deploy command

Also removed deployContainerCmd function. This will simplify the app's
container creation, instead of having to wait for the deployment to
finish, create an image an then run another container, we simply execute
both steps in one docker run.
provision/docker/provisioner: removing image creation on Deploy

Since now newContainer will do both steps at once (deploy and run the
application), there's no need anymore to create the image on this step.
