Separate README
Separate Dockerfile
Added case statement entries to allow devuan releases
Using the exist Dockerfile leads to missing keys for the container and
the debootstrap chroot. To use the existing image you could:
* Add a devuan sources.list and pull in the keys package and the devuan
debootstrap
* Add gnugp2 and apt-key to the debootstrap --include and add the key
via --keyring then after the debootstrap second stage use apt-key add
