DEPS bump to grab linter 0.1.17.

Adds:

* Fix to `public_member_api_docs` to check for documented getters when checking setters (#237).
* New `iterable_contains_unrelated_type` lint to detect when `Iterable.contains` is invoked with an object of an unrelated type.
* New `comment_references` lint to ensure identifiers referenced in docs are in scope (#240).
