* _old codebase_ before docker update

* before docker update, testing runnr

* docker update, testing the caching

* distributed job cargo homes

* distributed job cargo homes 2

* distributed job cargo homes 3

* dockerfile with gitlab checkout, audit uses template

* dockerfile gets repo in volume

* change builds_dir

* trying docker cache for repo

* repo cached automatically

* after script is not concatenated

* check sccache non-cacheable reasons nature

* watch cache

* log sccache

* log sccache 2

* debug log sccache

* fix debug log sccache

* fix debug log sccache 2

* debug log cache 3

* debug log cache 3

* trace log all sccache

* test wo cargo cache

* test w removed cargo cache

* report non-cacheable reasons, cargo cache is back and empty

* report non-cacheable reasons, cargo cache is back and empty 2

* report non-cacheable reasons, cargo cache is back and empty 3

* wrap into after_script

* restore CI tags

`qa` -> `linux-docker`
