Manuel Tiago Pereira 057cbacf8a Add support for legacy registries to pull_image(). ...

Since we now have several exceptions to the assumption that the
result of the pull would be on the last status line returned by
docker-py's pull(), I've changed the function so that it looks
through the status lines and returns what if finds on it.
Despite the repeated `break`s, the code seems simpler and a little
more coherent like this. From what I've checked using
`https://github.com/jlafon/ansible-profile`, the execution time is
mostly the same.
