Use codequality report with Runner's CI jobs

Initial issue description taken from !1255 (closed):

Configures code_quality job to use the dedicated artifact report entry. Additionally to the normal artifact and manual failing the pipeline in its last stage (since codequality report failures are currently not preventing MR from being merged).

The reasons:

1. Use our own tools
2. Make the codequality offences to be presented in the MR widget.
