Remove and simplify Integration monitoring

[squakez]

Requirement

As we have deprecated the advanced monitoring in favor of Camel Monitor Operator, we probably need to rework the entire monitoring checks when removing the deprecated code. This can include the issue tracked in #6787 and worked in #6848.

We should provide a big simplification as now we are only interested to track the Deployment condition and get any further info from Pod (for example, a failing container image).

This cannot be tackled in 2.12, as the deprecation was in 2.11. So, we must respect the proper time to remove the feature.
