Checklist
Changes proposed in this pull request
Update Docker configuration files to minimize the layers amount and make the code more readable.
upd:
The initial heredocs approach was replaced with RUN commands chained with
&& \
due to the unsatisfied buildkit requirements. I added missingapt-utils
package to resolvedebconf: delaying package configuration, since apt-utils is not installed
and set DEBIAN_FRONTEND to noninteractive. Also added a couple of cleanup instructions to minimize the image size.
