[RFE] Add CR's additionalPrinterColumns' info to the objects list (within CRD's details view)

[joaquimrocha]

Current situation

We do show extra information from the additionalPrinterColumns in the Custom Resource objects' details view, but we don't show them in the table where we're listing those objects, meaning it's more difficult for users to see those details right away.

Ideal future situation

We should show the additionalPrinterColumns in the CR objects table.

There are a couple of issues with this approach in the end.

1. The additionalPrinterColumns depend on the CR version. So we may not have the same columns for all CRs. A solution would be to split these out in different tables, but then the UX is not so great IMO.
2. We cannot control how many additional columns there will be and there are only so many we can fit horizontally. So it'd be preferable to either show them up to a number and have the rest configurable.

I am therefore lowering the priority of this issue until we figure out a good way forward.
