Create Dockerfile for Kronos

Docker has 3 kronos services, one for all, one for readonly, one for collector. When docker is run, all three are started. Three ports are mapped. The log directory is mapped to `/var/log/kronos`. Settings file at `/etc/kronos/settings.py` is mapped into the docker.
Wouldn't it make sense to put it at 8150 and you can change the makefile to whatever port you want? :stuck_out_tongue_closed_eyes:
