require-jsdoc fixer improvement: customizable fixer text

Would you be open for a Pull request, which changes the fixer of the require-jsdoc rule?

At the moment, the fixer is adding a comment like this: 
```
/**
 *
 */
```

I would like the comment to be something like: 
```

/**
 * TODO: fix jsdoc/require-jsdoc
 */
```
 
 So you can search in your IDE, which comments should be corrected.
