[tetianakravchenko]

What does this PR do?

Pod: use last_value instead of average. For counter average is not supported
Api server:

• remove 2 visualisation, because now when the aggregation was changed sum -> max we need to break it down by multiple fields, but the current limit is 4. Also it is indeed is quite a lot data per one visualisation, we need to rethink current visualisation

TODO:

• create an issue to readd removed visualisation

we need to break it down by multiple fields, but the current limit is 4.

Is this a Lens specific limitation? Is this something that should get removed?

yes, seems to be Lens specific, there is max 4 fields for the Breakdown, then Add field becomes inactive:

I would create a different issue and investigate how/if possible to reorganize those visualisation
