Bug 1304487 - Make incompatible mozharness actions a no-op when try syntax includes '--artifact'; r=armenzg Rather than clearing actions in volatile_config, add in actions from the artifact config's default_actions. Incompatible actions are then skipped based on 'forced_artifact_build' config value. MozReview-Commit-ID: IZuDvxcQ7cN
