kind: Rm push_args variable quotes

When using Docker, push image command fails because
the push_args var is interpreted as empty string, Docker
reject it as invalid variable and fails with the following error:
  $ docker push '' localhost:5000/ovn-daemonset-fedora:latest
  docker: 'docker push' requires 1 argument

Remove the push_args wrapping quotes.
