instead of dumping the journal , write it out over pyartiproxy and echo the link

• 
  see dumpjournal.sh
• 
  gcov-wrapper can output html , possibly zip up and upload
• 
  in addition, we might want to upload  /run/platform/display/compositor.log , ... some files (e.g. VAR we can add to lava testdef with known default)
• 
  needs env_dut.yaml
