osbuild-composer now uses socket activation instead of hardcoded paths
in the code. osbuild-worker is an http client therefore it uses only
service unit. osbuild-worker must be started after the socket is
created. osbuild-composer service requires osbuild-worker to run, because without
it no jobs can be started.
osbuild-composer is executed as a regular user (newly created
_osbuild-composer user) as opposed to the worker which must run as root
in order to execute osbuild itself
Keep main.go files under cmd/ and internal libraries under internal/.
This will allow us to add more exutables under cmd/ (whereas only one
was possible when main.go was kept in the root).
