CM Document for content types should display a section related to metrics

Problem/Motivation

When I view a CM Document that covers a content type, I should see a section for metrics.

• For nodes content types, I should see how many nodes of that type exist. (published and unpublished)
• For taxonomy vocabularies I should see how many terms there are.
• For blocks I should see how many block instances there are.
• paragraphs might be able to show how many instances of that bundle there are
• media should show how many there are of that type.

If the CM document is for a field, Nothing should show.
