Restructure "Eventing component" section

[RichieEscarez]

Align content with the developer flow and arrange content into logical sections.

View proposed nav structure

• For all moved or renamed files, add a redirect to that file's frontmatter (Ensure that all content affected by the nav changes gets a "redirect" #1925)
• Create a Eventing only install section
• Create new “Event consumers” section
• Create new “Event producers” section
• Create new “Debugging” section
• Organize “Debugging (and Observabiltiy)” content into new section

I think the eventing only install section is covered now in the docs here https://knative.dev/docs/install/any-kubernetes-cluster/ ? @carieshmarie wdyt? Can we check off that item in the list?

Reopening for now but we need revisit this

[abrennan89]

I think creating issues like this that are one big long list actually end up getting ignored a lot of the time because it's too much scope / too much like an epic rather than a single issue to track a docs change. Maybe try splitting the list up?

Note to self: Conceptual info re producers / consumers in this PR can be added: #3476

Note to self: Related to knative/ux#39

For observability and debugging, these require engineering input/work that are already tracked as other issues:

• Improve troubleshooting eventing docs #3044 debugging
• Document Observability support for Knative components and Knative services #2931 observability
  Checking these off the list for this issue

Once you split out the tasks from this issue (I removed some of the original list items and made them their own issues), what's left is a pretty generic request for information. I think just adding info about "event producers and consumers" out of context doesn't really add any value, so I'd like for us to close this one for now and revisit this when we have bandwidth to flesh out some more conceptual topics about Knative as a whole. Probably makes more sense to do this after we've split docs into different "guides" for different personas as well, so that we know what type of info is required.
