Description
Currently there's no out of the box way to set up a test with tracing turned on that would collect spans in a queue for further analysis. What is required now from the user is to either use a TestSpanHandler from Brave or ArrayListSpanReporter from OTel.
With the changes in this PR we're introducing an abstract concept of aggregating spans for Micrometer Tracing API.
In Spring Boot we would need the @TracingTest test slice that would turn on the @AutoConfigureObservability with tracing on and would register the TestSpanHandler as a bean.

Research direction
Start by reviewing the proposed @TracingTest slice, @AutoConfigureObservability, and the related Micrometer Tracing PR and issue. Determine how the slice should enable tracing and register Brave's TestSpanHandler as a bean. Done means a test can use the slice and inspect collected spans without manually configuring a handler.
