This example demonstrates that tag annotations can also be provided
by stage methods and stage classes.

Providing tags through steps rather than tests has the benefit that
all new tests using these steps will automatically be tagged accordingly.
Furthermore, it allows tagging many tests by only tagging an individual
step method or class.
