A big commit to fix more things, see details

- ingress can now have annotations
- configmaps are better named and there is a label to know from where
  the content is taken
- fixed bad "nil" pointer checks
- we force to not resolve paths from compose file, this should be a
  problem when we call the compose file from outside. So, TODO: check
  this!
- the "project" label is now the Chart Name, not a static string
- minor fixes
