[API] Regenerates APIs with ignore 404 fix

Adds option to use ignore: 404 in `clear_scroll`.
As a side fix, it also fixes security.get_role and
watcher.delete_watch which also supported the feature to ignore 404,
but the parameters were coming empty, so they'd return a boolean
instead of the Response from Elasticsearch.
