There are some back links to install connectors and offloaders. I'll resolve them separately in another PR.

Why remove bin/pulsar-daemon start standalone part? Is it a rare use case?

@Anonymitaet Have you previewed your changes to ensure everything goes as expected?

Aha, I preview each change in batch. It's OK that I attach some screenshots. I didn't do it in the first place because it's almost a new page longer than one screen and I'd prefer the reviewers can preview themselves. Also, it's easily outdated as the review is in progress.
