moving from rc to deployment (#951)

As deployments (and replica sets) are replacing the rc primitive, I thought of moving this manifest to deployments, too.

The `kind: list` thingy doesn't work here, as it has problems with using `extensions/v1beta1` so I used `---` to make a valid YAML list.

Other than that nothing has changed. The selector had to be slightly modified to include `matchLabels:`.

I've tested this already, and it works for me.
