new rule: add config parameters to missing-jsdoc rule

[ian-craig]

While jsdoc-format is enough to require correct formatting of docs, there’s no rule that I know of to ensure the docs exist in the first place. It would be useful to have a rule that requires they exist and not be blank for a configurable list of major items (default to everything?), such as:

• classes
• exported variables
• functions
• member variables
• member functions
• ...anything else?

Thanks for the idea. This is very similar to #33. I will close that one as a duplicate.

• Modules
• exported classes
• all classes
• exported interfaces
• interfaces
• interface members
• exported variables
• functions
• exported functions
• public member variables
• all member variables
• public member methods
• all member methods

From a limited TSLint knowledge and reading https://github.com/Microsoft/TypeScript/wiki/Using-the-Compiler-API, I think this requires the type checker for symbol.getDocumentationComment(). Yes?

@JoshuaKGoldberg I am pretty sure you can get the comments without using the type checker... but if you use the type checker then you probably get a much more structured object and would not have to use RegEx to pick apart the comment. Your suggestion is probably the way to go.

@ian-craig I think this issue is resolved?
