As a user, I want to be able to see a summary of all logs messages after harvest execution completes

[jordanpadams]

💪 Motivation

...so that I can easily tell if products failed, if there are warnings I should check out, etc.

📖 Additional Details

⚖️ Acceptance Criteria

Given a bundle with a product label that contains something that will cause an error in harvest
When I perform a harvest execution on that bundle that includes that product
Then I expect to see a part in the summary that includes a number of errors (and warnings) that occurred during the execution.
