Task #2124

Make CzechIdM image smaller
100%
Description
The image is about 860MB large which is just awful.
Analyze and correct if it is possible.

Easiest to correct seem to be the 130MB increase in chown on layer 3203c39515aa . We do not use COPY --chown for portability reasons but using COPY and RUN chown in sequence makes overlay2 construct new layer with the same file. I think we do not need to do the chown at all because all we do with the WAR is that we read it (and by default it will have 644 permissions so we should be good).

The chown really was unnecessary so I removed it. Image size fell from 860MB to 730MB. Tested, everything works fine.

I was also looking at the tomcat image and the only place we could optimize is the yum exec on layer c3dc4b1326b0 .
But that layer contains yum update which we cannot drop for security/updates reason - so we are stuck there. I think this is the most we can do for now.
