Add before_script_actions process to make PHPStan and ESLint fail on demand

Problem/Motivation

For the phpcs and cpsell jobs we have added a before_script action to make these jobs fail on demand from the upstream pipeline. The same functionality is needed for phpstan and eslint, as these jobs produces artifacts we are creating.

Ideally, we should also have the same functionality for composer-lint and stylelint but these are less important because they do not produce custom artifacts.

Proposed resolution
