disable coveralls.io comments

It is starting get a little bit annoying that coveralls comments to for every push to PR.

Maybe we should consider disabling coveralls comments (this can be done in coveralls.io settings). Increase or decrease of coverage for PR can be still seen in status checks.

I think that only one who has permission to change coveralls.io settings are repository admins (@sebgoa)
