docs: load balancer and registry authentication

[burgerdev]

Add some missing details with respect to load balancers and registry authentication.

I have some more content for the How-To section in mind:

• Exposing the Coordinator with Ingress/Gateway-API
• Working with genpolicy settings
• Determine correct reference values
• Manual recovery of persistence

[burgerdev]

I need to fix the publish job and I also noticed that there's some more content I need to add. Converting to draft for now, will let you know when I'm ready.

@m1ghtym0 ready for review!

[m1ghtym0]

Based on this description, you need to already know what you're doing, but if you build a bare-metal setup, that's a fair assumption. So that's fine for me.

[burgerdev]

I do have an example deployment for this, do you think it's worth adding here?

[m1ghtym0]

I think one the one hand this is only related content that's not directly connected to Contrast and having such example means we would need to maintain and ideally test it.
On the other hand, that would definitely be a good starting point for folks setting up a bare-metal deployment. Could be part of the examples section.
Depending if your verdict if such example would be maintainable, I'd say why not adding it to the examples section?:-)

[m1ghtym0]

Can/Should be done independently of this PR though.

[burgerdev]

Not sure which examples section you're referring to. I lean towards adding some yaml I've written for a demo right here, but I don't think this should be a maintained feature - we should rather invest that energy into making registry authentication work!

[m1ghtym0]

Was expecting this to be quite a lot of yaml. Hence the thought of an individual page in the Contrast examples section. If it works inline, of course, as you say.

[burgerdev]

As discussed privately, won't add the example because it's too lengthy.
