Migrate to SARIF output

Linters current produce JUnit output as per !9 (merged). However we can do much better, by using quality reports via SARIF output reports. This is not supported yet within gitlab yet (and may end up partially an ultimate feature).

Anyway junit output is very restricted in how it is displayed to the user, and quality output is far superior, as it will reply within the MR and code where it is failing.
