[GENERIC] move from registry.hub.docker.com to docker.io

`registry.hub.docker.com` needs authentication now, in contrary to

As OOM deployments is unauthenticated when using docker hib repository,
all OOM deployments is broken.

`docker.io` seems to be still OK with unauthenticated requests so let's
move to this endpoint.
