Rule proposal: require-description

[ota-meshi]

Please describe what the rule should do:

This rule reports directive comments without description.

What category of rule is this? (place an "X" next to just one item)

[ ] Warns about a potential error (problem)
[ ] Suggests an alternate way of doing something (suggestion)
[ ] Enforces code style (layout)
[X] Other (please specify:)

Provide 2-3 code examples that this rule will warn about:

/* eslint-disable */
/* eslint-disable rule-name */
/* global _ */
/* eslint-env node */

No warning is given if the directive comment contains an description.

/* eslint-disable -- description */
/* eslint-disable rule-name -- description */
/* global _ -- description */
/* eslint-env node -- description */

May need an option to set whether or not to warn depending on the type of directives.
