Intellisense should inherit documentation for Interfaces.

[patrick-janeiro]

When implementing an interface the intellisense feature is capable of detecting the description of the interface however it does not carry over any tags such as @param and @returns.

Below is a picture of an example:

You can see that the description is properly shown however the param and returns tag is not.
What is expected:

Tested with TS 3.3.0-dev.20190119

Example code:

interface IFoo {
    /**
     * Does stuff 
     * 
     * @param x An argument
     */
    bar(x): void
}

class Foo implements IFoo {
    bar(x: any): void {
        console.log(x)
    }
}

Request is to have the quickInfo also include the jsdoc tags property for the implementation method

There is a duplicate of this somewhere but I can't find it at the moment.

I wonder if this is related to #28470
Here it is about classes implementing an interface, there it is about something extending an interface.
But it look suspiciously similar otherwise.
