Parse and report syntax errors for hadolint #958
Description
I'm using hadolint and ale to lint my dockerfiles.
When the syntax of the keywords are ok, it shows me hints what to improve - fine!
But when the Dockerfile contains a line starting with a non recognized keyword or junk text, ale won't show any error or hints unfortunatly.
