Base image changes for drop-root
The reason we are doing drop root is so that a network exposed
software component (i.e. glance) cannot be used to affect the
immutability of the container which it runs in. I have tried
several different approaches and this is the only approach which
puts glance in PID=1 while ensuring no files may be written by
the glance process in the container image except for the log files.
