Generic codebase improvements

This is a ~"feature proposal" about generic improvements that we can work on:

• upgrade pipelines in order to use codequality
• make the runner go gettable
  • remove runner circular dependency on itself (it has to build himself in order to provide the gitlab helper inside the bundled docker image)
• running test with race condition detector flag -race
  • fixing existing race conditions

Some of that items may be worth a dedicated issue.
