feat: rosa submariner

tests related to the integration of submariner in a multicluster deployement (https://github.com/camunda/team-infrastructure-experience/issues/253)

Readme looks good 👍.
I didn't test it out but the steps make sense and everything is detailed.
Agree, would probably not merge it for the time being but on a branch is good to potentially in the future turn this into a fully supported approach + potential alignment with submariner for other providers.

Looks good to me as well! Thanks for creating a detailed readme for how to recreate the setup, really well done 🙇 Let's also convert this to draft so it's not merged by chance.

Thanks, @maxdanilov and @Langleu, for the feedback.

I’ve moved the example to an examples folder and added a note indicating that it’s intended as a proof of concept (PoC).

I’m okay with keeping it on a dedicated branch, but it might need to be synchronized with the main branch over time. What are your thoughts on keeping the examples folder on the same branch?

[maxdanilov]

I think unless we're ready to commit to these examples as to something we vouch to maintaining and ensuring they're always functioning (and customers picking these up), we should keep in on the branch. I'd say let's keep it as is on the branch/draft PR and productise as a part of the OpenShift dual-region epic.
