Revert "Caddy 0.1"
This reverts merge request !243
First of all, I apologise for revert like this, but it was to prevent certain code (against slapos standards) stay on master long enough to provide bad example.
On master, we have too many proof of concepts which introduce bad behaviours, and those bad behaviours are reproduced over and over.... and I want to ensure the code in master is always as good as they can be. (nothing prevents keep developing on a branch).
And also, please, let's respect @kirr review's with the suggested changes, and I prefer do now what @kirr suggested rather them later, and do before merge on master. In particular, it is a crime to introduce a non-reproducible feature, with everything pinned.
I also want stack for caddy, as it is the way we want to use it. A software release "caddy" is, in general, meaningless as it works only as dummy example, with no practical function currently (neither in future).
PS.: I'm available for further discussions.
