rolling_update: run registry auth before upgrading

There's some tasks using the new container image during the rolling
upgrade playbook that needs to execute the registry login first otherwise
the nodes won't be able to pull the container image.

Unable to find image 'xxx.io/foo/bar:latest' locally
Trying to pull repository xxx.io/foo/bar ...
/usr/bin/docker-current: Get https://xxx.io/v2/foo/bar/manifests/latest:
unauthorized
