Switch to a smaller base image for jx

[hferentschik]

The default image used for the jx image is centos:7 which clocks in at around 200 MB. It would be nice to have a smaller base image, eg alpine or busybox.

There are concerns around alpine and DNS resolution though - gliderlabs/docker-alpine#255
