Suggestion: make integration tests less chatty

Overview of the Suggestion

When running the API E2E test suite, you get a lot of unnecessary output. It slows down execution as it needs to be printed and makes debugging failures much harder. We should only output more detailed information when tests fail or someone flips a switch to enable more verbose output everywhere.

What kind of user is the suggestion intended for?
Developer

What inspired this idea?
When adding another API test I was once again digging through a lot of superfluous output.

What existing behavior do you want changed?
Be less chatty, only when it matters tell me details.

Any brand new behavior do you want to add to Dataverse?
Nope

Any open or closed issues related to this suggestion?
None that I know of.

Are you thinking about creating a pull request for this issue?
Aye.
