Subject: [PATCH] Changed Optional to Positional arg in zun pull

zun help pull
usage: zun pull -r <repo>

Pull an image.

Optional arguments:
  -r <repo>, --repo <repo> image repo

repo is required argument so we can make
it positional and can make it like docker:

docker pull cirros
zun pull cirros

Closes-Bug: #1658674
