New rule: require-throws

[0xCLARITY]

Motivation

The same way we have require-returns and require-param, I think there would be value in a require-throws rule.

Current behavior

Currently, given a function that has a throw keyword, that throws an Error, I have no way to require documenting that the function throws an error using ESLint.

Desired behavior

If a function contains the throw keyword, require having a @throws in the JSDoc for the function.

Alternatives considered

Wouldn't catch all cases naturally, but would still be of good value. This might be a good first issue as one could follow the require-returns rule.
