Add lint job to the check pipeline
This is a Zuul job which will run |web-ext lint| on the extension's
//src directory to see if there are any lint errors.
If any lint error is returned, the check will fail. Otherwise, if it
successfully passes the lint check (meaning only warning or softer
messages were shown), the check will pass successfully.
