Rename sloppy to jsdoc3

[Constellation]

Basically doctrine supports Closure compiler tags.
But jsdoc3 tags are useful, so we need to support it.

Currently jsdoc3 style optional param is supported when sloppy flag is on. This is not suitable name. We should rename sloppy to something like jsdoc3.

Thanks for this issue. We have decided to officially end-of-life JSDoc support in ESLint. As a result, this repository and project will no longer be maintained.

Thanks for understanding and we apologize for any inconvenience.
