Breakdown views: Provide exploration alternatives based on the user intention

[matyax]

The current breakdown UI is focused on metric queries, with charts showing the trends over time of different labels and fields, which can be helpful when you don't know what you're looking for or you're trying to identify something that "looks off".

But we don't provide any UI when you have an idea of what you're looking for and you're interested in keys and values, not on trends or how data looks over time.

One idea could be to have a toggle to focus the breakdowns on the type of exploration that the user requires at a particular time.
