CLOUDP-238465: remove ownership detection

[s-urbaniak]

Given the current research we are confident that the current ownership detection code base won't survive in its shape and form.

This removes ownership detection for good from the current code base.

Note for reviewers: review commit by commit, this has been carefully sanitized to have the removal of ownership detection live in its own commit. For merging I also vote for not squashing but keeping the commit history from this PR.

Separating this as separate PRs will be very hard as the commits are partially not compilable.

The more code we remove/optimize, the more racy behaviour of our tests bubble up:

I experienced the same in https://github.com/mongodb/mongodb-atlas-kubernetes/pull/1595 so this also needs similar fixes 😞

[s-urbaniak]

ok, looking at test/int/deployment_test.go, the whole code doesn't handle conflict resolution during Update()s so we need to fix it here as well.

[s-urbaniak]

yeah, now the CI is green, I'd still like to add conflict resolution in the integration test here before we merge.

[s-urbaniak]

as discussed with @josvazg: I will use this PR as a guinea pig for conflict resolution but will merge this PR only after another PR fixing updates in the first place.

[s-urbaniak]

1/3 panics fixed, moving to the next one.

Note: we want to merge this after https://github.com/mongodb/mongodb-atlas-kubernetes/pull/1622 in order not to amplify flakes.
