add apk cache and simplify named volumes

- apk supports caching of packages for reuse on next run. This is the
  prefered way and should be relativly fast compared to other package
  magenagers. This also removed the need for other named volumes which
  need to be setup and maintained on each run.
- correcly set perm of volume mount points
