Bug Report

With #4177. There is a confusion on grafana being isRequired while jaeger being not, even though they do the same things. The change would be to remove isRequired for grafana and update the tests as they expect grafana field to be there always.

Also, we are not really using grafana and jaeger fields, and just checking if they are empty. Using a boolean would be a better choice here.

What is the issue?

How can it be reproduced?
