Description of change
The second argument to "assert.throws" is usually a validation RegExp or
function for the thrown error. However, the function also accepts a
string and in this case it is interpreted as a message for the
AssertionError and not used for validation. It is common for people to
forget this and pass a validation string by mistake.
This new rule checks that we never pass a string literal as a second argument
to "assert.throws". Additionally, there is an option to enforce the
function to be called with at least two arguments. It is currently off
because we have many tests that do not comply with this rule.

@targos would you be willing to manually backport to LTS?

I will. It requires that we backport the other PRs I did earlier to fix the assert.throws issues.
