MAINTAINER is deprecated

Problematic code:

FROM busybox
MAINTAINER Lukas Martinelli <[email protected]>

Correct code:

FROM busybox
LABEL maintainer="Lukas Martinelli <[email protected]>"

Rationale:

MAINTAINER is deprecated since Docker 1.13.0: https://docs.docker.com/engine/deprecated/#maintainer-in-dockerfile
