Remove option to refer to queue selector as experimental
In #147 (closed), we changed the
--experimental-queue-selector option to be just
--queue-selector, but we support either. In this issue, we can remove the old version. To do so, we'll need to grep for this issue (
- The Rails app.
- Our CNG images.
And remove / simplify as appropriate.
We also need to mention this in the monthly release post.
