Change some form handling rules

jsx-a11y/label-has-for is deprecated in future versions of eslint so we should disable it now in favor of label-as-associated control

fs-styles currently does not support nesting, so the default `assert` setting of both is too strict. Switching to `either` allows either nesting or using a `for` or `htmlFor` parameter. Until we move off of fs-styles this will prevent many spurious linting issues.
